Voltage fed zero-voltage zero-current switching PWM DC-DC converter
2008 13th International Power Electronics and Motion Control Conference, 2008A new zero-voltage zero-current switching full-bridge phase-shifted PWM converter with controlled output rectifier is presented in this paper. IGBT switches are used in the high-frequency inverter of the DC-DC converter. Zero-voltage turn-on and zero-current turn-off for all power switches of the inverter is achieved for full load range from no-load to

A zero-voltage transition boost converter using a zero-voltage switching auxiliary circuit
IEEE Transactions on Power Electronics, 2002A soft switching boost converter with zero-voltage transition (ZVT) main switch using zero-voltage switching (ZVS) auxiliary switches is proposed. Various operating intervals of the converter are presented and analyzed. Design considerations are discussed.

A review of zero-voltage switching and its importance to voltage regulation
2017 IEEE International Conference on Power, Control, Signals and Instrumentation Engineering (ICPCSI), 2017Step-down (“buck”) DC-DC voltage regulator circuit design is getting harder because power density (W/m3) is rising, DC power supply voltage levels are rising, and silicon voltage demands are dropping in order to increase efficiency. The difference between the supply voltage and that required by the silicon creates a big drop across the regulator ...

Effect of switch capacitance on zero-voltage switching of resonant converters
PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003The authors present an analysis of the series-parallel resonant power converter (SPRC) that includes the capacitance of the switches. New DC characteristics are obtained, and the regions where the converter operates with zero voltage switching are determined as a function of the switch capacitance.

Zero voltage soft switching converter with high input voltage
[Proceedings] Thirteenth International Telecommunications Energy Conference - INTELEC 91, 2002High input voltage to a converter decreases its efficiency because turn-on loss of a main switch increases in proportion to the square of the input voltage. To decrease turn-on loss, the authors examined a zero-voltage-switched quasiresonant power converter. It causes severe voltage stress, which is about four or five times the input voltage, on a main

Zero-voltage-switching converters with multi-resonant bipolar switch
Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002Full-wave mode operation of zero-voltage-switched (ZVS) power converters may be losslessly implemented by splitting the resonant capacitor across both the active switch (MOSFET) and the series diode. By appropriately choosing the relative size of each capacitor, charge otherwise trapped inside the MOSFET output capacitance at turn-on may be ...

This paper proposes a voltage unbalance compensation method of series-connected switching devices for high voltage application such as DC distribution systems. In the series connection, a turn-off voltage unbalance occurs in switching devices due to a parasitic parameter mismatch and a switching timing mismatch among switching devices. In this paper, a

Charge control for zero-voltage-switching multiresonant converter
IEEE Transactions on Power Electronics, 1996The operation of zero-voltage-switching multi-resonant power converters (ZVSMRCs) limits the use of peak current-mode control. The charge control technique is found applicable to ZVSMRCs for improving dynamic performance. Charge control compares the total charge of the switch current to the control voltage to modulate the switching frequency. Since the

A simple zero-voltage-switching boost converter
Proceedings IEEE Southeastcon '98 'Engineering for a New Era', 2002In this paper, a new type of PWM boost zero-voltage-switching converter is presented. The new soft-switching converter is formed by adding only two auxiliary components to a conventional boost converter, namely: an active switch and a resonant inductor. The voltage stresses on both the main and auxiliary switches are fixed at V/sub g/+V/sub o/ and they
