This paper deals with thedesign of full bridge boost converter with a fly back Snubberfor high conversion ratio, high output power, and soft start-up capability. The fly back Snubber is the combination of a capacitor, a diode, and a fly back converter. It clamps the voltage spike caused ...
The Full-Bridge Converter block implements a full-bridge power converter. You can choose from four model types: Switching devices— The converter is modeled with IGBT/diode pairs controlled by firing pulses produced by a PWM generator. This model provides the most accurate simulation results. Switch...

To meet this high-efficiency standard some designers have turned to using a phase-shifted, full-bridge converter with synchronous rectifiers for the DC/DC portion of the power system. This is because this type of converter can achieve zero voltage switching (ZVS) with reduced conduction losses. ...
This is further fed into a single phase full bridge inverter which convertes the DC voltage into discrete AC pulses using IGBT diodes and a switching logic. Additionally, a Pure Sine Wave Converter circuit (PSWC) is used to convert the discrete AC pulses into a pure sinusoidal waveform. The...
