    A Three-Winding Coupled-Inductor High Step-Up Boost Converter with an Active-Clamp Circuit

    Danesh Amani, Reza Beiranvand, MohammadReza Zolghadri
    Conference Paper2021 12th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC) , 2021 February 2, {Pages 05-Jan }

    Abstract

    A new high step-up boost converter with an active clamp circuit to eliminate voltage spike caused by leakage inductor is introduced in this paper. The introduced power converter has a high voltage gain for variable input voltage from 48V to 80V. Since both main and auxiliary switches turn on with zero voltage switching (ZVS) and all the diodes turn off under zero current switching (ZCS) condition, switching losses and EMI noises are strongly degraded. Therefore, the converter’s efficiency is improved significantly. Simulation results show a 96.4% peak efficiency and 95.4% average efficiency. The proposed topology is suitable for low-input-voltage and low-output power applications such as solar panels or fuel cells applications.

    Conference Paper2021 12th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC) , 2021 February 2, {Pages 06-Jan }

    Abstract

    In this study, a new LLC resonant converter for high-voltage high-power applications is introduced. The introduced power converter is a two-phase interleaved full-bridge based that uses a transformer with secondary and tertiary windings to obtain higher output voltage. Zero voltage switching (ZVS) at MOSFETs turn on and zero current switching (ZCS) for all the output diodes at turn off are achieved for a wide range of input voltage (100 V–200 V) and output power (200 W–1500 W) variations. Simulation results show a 95% peak efficiency.

    Abstract

    In this paper, the analysis, modeling, comprehensive controller design for the three-level dc/dc converter (TLC) is discussed. Bidirectional three-level converters have a wide range of applications, such as those used in electric vehicles (EVs). High efficiency, lower inductor size than similar and competing converters distinguish TLC for researchers. Symmetry analysis in TLC, linearization model method and linear model approximation from non-linear model is evaluated by using Matlab/Simulink program. Zero and pole behavior, open and closed loops of TLC for load and duty cycle changes and duty cycle constraints in non-ideal model is stated in this paper. Finally, a control scheme for voltage balance between series capacitors are presented.

    Conference Paper2020 11th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC) , 2020 February 4, {Pages 06-Jan }

    Abstract

    Output voltage of PV panel and Fuel-Cell are low and shading effect also influence on output voltage level, so a high gain dc-dc stage usually is needed. In this paper, a high step-up “improved -Z-Source” dc-dc converter is proposed which based on “improved -Z-Source” ( ). In comparison with existing topologies, the proposed topology has higher voltage gain and higher efficiency. Moreover low voltages stress is applied on the switch under the same conditions. Also using a single magnetic core instead of several magnetic cores in coupled inductor are the advantages of this topology. Shared ground between input and output cause simple control and reduce complexity. Finally the proposed converter draw continuous current from input

    Abstract

    Due to the ever-expanding use of light emitting diodes (LED) lamps and the necessity of constant current to operate properly, a drive circuit is required for these types of lamps. Also, power factor correction (PFC) to eliminate harmonics, is required and must be included in these types of drivers based on the existing standards. Soft switching can effectively reduce the switching losses and electromagnetic noise. Consequently, high switching frequency operation is possible which reduces the converter weight and size, effectively and high power density is achieved. In this paper, continuous conduction mode (CCM) operation of a single-stage boost-flyback converter with active-clamp for LED driver applications is introduced. Its CCM operation

    Conference Paper2020 11th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC) , 2020 February 4, {Pages 06-Jan }

    Abstract

    In this paper, an improved phase-shifted full-bridge dc-dc converter with current doubler rectifier for electric vehicles is introduced. By use of coupled inductors as opposed to output filter inductors, the circulating current, RMS current, and voltage stress on output capacitor are reduced. Therefore, the zero voltage switching range is extended and higher efficiency from light load to full load is obtained. The two coupled inductors which have small secondary inductors are used in proposed converter. Thus, neither extra components nor auxiliary circuits are needed which leads to control simplicity and prevent extra costs and bulky size. As a result of this topology, the required energy for soft switching, voltage stress across secondary

    Abstract

    Lithium-Ion batteries and super capacitors traditional energy storage systems(ESSs) need a voltages balancing circuit to remove voltage imbalance and one bidirectional dc-dc converter to control the charge process. Since these two separated circuits need several sensors, switches, inductors and multi windings transformer, the complexity and volume of ESS is boosted. In this paper, a self-equalized charger for lithium-ion batteries is proposed which consists of a phase-shifted full bridge dc-dc converter for charging operation and a voltage multiplier for eliminating voltages imbalance. Owing to integrated structure of the proposed circuit, complexity and volume of the system are reduced. By using phase-shifted method, the converter experien

    Abstract

    Due to the energy storage cells low voltage, such as batteries and super-capacitors, it is often necessary to connect them in series to form a string. Generally, these components are sensitive to over-voltage. Also, due to the inevitable differences in these devices, their charging and discharging processes cause their voltages to be different. This problem leads to inappropriate use of capacity, short life time, and even explosion. To overcome these problems and also to achieve safe and economic operation of these storage devices, employing voltage equalizer converters is necessary, in practice. The proposed converter can overcome the above-mentioned problems and it has less components than the conventional voltage equalizers, smaller dime

    Journal Paper , 2020 November 29, {Pages }

    Abstract

    In this paper, an improved phase-shifted full-bridge (PSFB) dc-dc converter with coupled inductors and a current doubler rectifier (CDR) for battery charger applications in electric vehicles (EVs) is proposed. By using two coupled inductors as opposed to traditional output filter inductors, the RMS currents, the circulating current, and the voltage stresses on the secondary side are decreased. Besides, the zero-voltage-switching (ZVS) operation range is lengthened. Therefore, higher efficiencies are achieved. The two recursive inductors in the primary side have small and negligible values compared to the output inductors and, consequently, neither complex control systems nor extra components (like auxiliary circuits and active clamps) are n

    Abstract

    Conventional energy storage systems (ESSs) such as super-capacitors and lithium-ion batteries require voltage equalization systems to eliminate voltage imbalances, and bidirectional dc-dc converters to complete the charging process. These separated systems require some sensors, inductors, switches, and transformers. Consequently, the ESSs volumes, prices, and their complexity are dramatically increased by increasing the required series connected batteries count. Here, a self-equalized battery charger is proposed for lithium-ion batteries by combining a voltage multiplier (VM) and a phase-shifted full-bridge (PSFB) dc-dc converter. In the proposed self-equalized battery charger, the voltage multiplier eliminates the voltage imbalances and th

    Conference Paper2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC) , 2019 February 12, {Pages 272-278 }

    Abstract

    This paper presents a Flying-Capacitor converter above its resonant frequency considering zero-voltage switching (ZVS) realization and voltage regulation issue due to wide input voltage and output power variations. A new multi-level Flying-Capacitor (FC) dc/dc converter is candidate among the other proposed topologies with lower power device count and soft switching characteristics that results in lower electromagnetic interference and switching losses. ZVS operation under the continuous conduction mode (CCM) operation has achieved undeniable benefits in switching losses and therefore a higher efficiency. In the MOSFET-based converters, the ZVS operation causes lower switching losses in contrary to the wide used zero current switching (ZCS)

    Conference Paper2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC) , 2019 February 12, {Pages 230-235 }

    Abstract

    This paper presents a resonant switched capacitor converter (SSC) above its resonant frequency to achieve zero voltage switching (ZVS) operation and overcome its voltage regulation issue. The ZVS operation under the CCM operation mode reduces switching losses and improves the converter efficiency more than zero current switching (ZCS) operation below the resonant frequency in MOSFET based converters. In addition, under the CCM operation mode the output voltage can be regulated as the input voltage or load current varies in a wide range. The symmetrical dual structure proposed converter causes the input current ripple and output voltage ripple to be reduced more in contrary to previous researches. Therefore, the input filter and output capac

    Abstract

    In this paper, a high step-up quasi-resonant dc-dc converter, based on an interleaved diode-capacitor structure, is introduced and analyzed. High voltage gain is obtained by the use of a diode-capacitor network. Soft switching condition, which includes zero-current switching (ZCS) or zero-voltage switching (ZVS), is resulted for all semiconductor power devices by quasi-resonance technique created by input inductances of the converter along with snubber capacitors across the switches. Reverse recovery problem of diodes is alleviated because of ZCS condition. Then, the switching losses have been reduced considerably and the converter efficiency is improved. With soft switching characteristic, switching frequency can be increased and subsequen
