A built-in input filter full-bridge converter (BIFFBC) for high-power applications, employing the transformer leakage inductance, two clamp diodes and two cross-coupled capacitors, is proposed. This configuration is equivalent to a conventional PWM full-bridge converter (PWM FBC) with an input filter. In addition to performing the input filter function,

Full-Bridge Transformerless PV Grid-Connected Inverters
2020The CMV analysis model and three rules of LC elimination are discussed in Chap. 2. One of the conclusions is that Rule 1 can be used in full-bridge TLIs. This chapter discusses the application of Rule 1 in full-bridge TLIs, including LC elimination by only decoupling the PV arrays with the grid and clamping the potential of the freewheeling path ...

Pseudo-resonant full bridge DC/DC converter
1987 IEEE Power Electronics Specialists Conference, 1987This paper proposes a new dc/dc converter topology which combines the ease of control and wide range of conventional dc/dc converters, with low switching losses, low dv/dt and low EMI that is typical of zero voltage switched resonant converters. Consequently, the ratings of these components are substantially lower than for similarly rated resonant ...

A novel soft-switching full-bridge converter
2009 International Conference on Power Electronics and Drive Systems (PEDS), 2009Inserting an auxiliary switch to the conventional hard-switch full-bridge topology, a novel soft-switching full-bridge converter is proposed. Instead of the main switches, the auxiliary switch is pulse-width modulated to regulate the output voltage and soft-switching operation of the main switches can be easily achieved over full line and load ranges ...

Single-stage SVS PWM full-bridge converter
IEEE Transactions on Aerospace and Electronic Systems, 2003A new soft-switched ac-dc single-stage pulse width modulation (PWM) full-bridge converter is proposed. The converter operates with zero-voltage switching (ZVS), fixed switching frequency, and with a continuous input current that is sinusoidal and in phase with the input voltage.

A new ZVS-PWM full-bridge converter
24th Annual International Telecommunications Energy Conference, 2003A full-bridge converter which employs a coupled inductor to achieve zero-voltage switching of the primary switches in the entire line and load range is described. Because the coupled inductor does not appear as a series inductance in the load current path, it does not cause a loss of duty cycle or severe voltage ringing across the output rectifier. The

Single Inductor Dual Buck Full-Bridge Inverter
IEEE Transactions on Industrial Electronics, 2015A new single inductor dual buck full-bridge inverter is proposed in this paper. The inverter is improved on the basis of a dual buck inverter, and it retains the advantage of a no reverse recovery of body diode. The dc voltage utilization rate can be increased by adopting the voltage commutation bridge instead of the voltage-dividing capacitors in the ...

Zero-Voltage Switching in Full-Bridge Converter
Australian Journal of Electrical and Electronics Engineering, 2008This paper presents a comparison study of circuit topology of the voltage source type zero-voltage soft-switching (ZVS) full-bridge DC-DC power converter with an isolated high-frequency transformer employing phase-shift control. The switching power losses and voltage stress on the active devices are considerably reduced. A prototype operating at 10kHz,

Zero voltage switching full - Bridge converter topology
Intelec 2010, 2010This paper describes a version of the Phase Shifted Full Bridge (PSFB) converter topology that achieves Zero Voltage Switching (ZVS) of the primary side controlled switches over a very wide load range, has minimal loss of output voltage due to commutation delay, that reduces the excess current flowing through the transformer and primary switches during

A Novel Zero-Voltage-Switching PWM Full-Bridge Converter
2007 IEEE Power Electronics Specialists Conference, 2007Introducing resonant inductance and clamping diodes into the full-bridge converter can eliminate the voltage oscillation across the rectifier diodes and increase the load range for zero- voltage-switching (ZVS) achievement. The resonant inductance is shorted and its current keeps constant when the clamping diode is conducting, and the clamping diodes ...
