A Novel ZCS-PWM Flyback Converter With a Simple ZCS-PWM Commutation Cell
IEEE Transactions on Industrial Electronics, 2008This paper proposes a novel zero-current-switching pulsewidth-modulation (ZCS-PWM) flyback dc/dc converter using a simple ZCS-PWM commutation cell. The main switch and auxiliary switch operate at ZCS turn-on and turn-off conditions, and all uncontrolled devices in the proposed converter operate at zero-voltage-switching (ZVS) turn-on and turn-off.

SOFT-SWITCHING PWM CONVERTER TECHNOLOGIES
Journal of Circuits, Systems and Computers, 1995The switched-mode power conversion technologies have evolved from the basic PWM converters to resonant converters, quasi-resonant converters, multi-resonant converters, and most recently, to soft-switching PWM converters. In this paper, several typical resonant techniques and several soft-switching PWM techniques are reviewed, and their merits and ...

PWM converters with resistive input
IEEE Transactions on Industrial Electronics, 1998An average modeling methodology is proposed for deriving pulsewidth modulation (PWM) programming rules that cause DC-DC converters to look resistive at the input terminals. The method can be useful in the design of active power factor correctors that do not need to sense the input voltage.

IEEE Transactions on Industrial Electronics, 1998
A modified zero voltage transition pulsewidth modulation (ZVT-PWM) Cuk converter is proposed in this letter. Better robustness, smaller minimum duty ratio, and lower turn-on loss are obtained in this converter. No additional component is needed compared with the conventional ZVT-PWM Cuk converter.

2014 International Power Electronics and Application Conference and Exposition, 2014
PWM converters have been widely applied for power processing and they are typically the stems of other types of converters, such as quasi-resonant and multi-resonant converters. Development of the PWM converters has been spanning over a century, starting from the buck converter. The well known PWM converters include buck, boost, buck-boost, Cuk, SEPIC,

The stability of a chaotic PWM boost converter
International Journal of Circuit Theory and Applications, 2011AbstractA novel chaotic pulse‐width‐modulation (PWM) boost converter has been previously proposed to reduce electromagnetic interference (EMI) in DC–DC converters, where the circuit design and simulations have been conducted, but the problems such as the mean value estimation of state variables for circuit parameter design, the ripple estimation of the

New PWM-Controlled GTO Converter
IEEE Transactions on Power Electronics, 1985A new pulsewidth modulation (PWM)-controlled GTO converter circuit is proposed. An auxiliary circuit capacitor is used to treat the commutating energy in the main circuit and to clamp the commutating impulse voltage at the desired level with the fundamental power factor of unity. An analysis of the circuit operation is verified experimentally.

Analysis of a PWM-resonant converter
IEEE Transactions on Aerospace and Electronic Systems, 1997When a parallel resonant tank is excited by a bipolar current pulse train a sinusoidal voltage develops across the tank whose amplitude depends on the duty cycle of the pulse train. An isolated secondary can be derived by applying the tank voltage to an isolation transformer whose magnetizing inductance acts as the resonant inductor of the tank circuit.
