Abstract

The main aim of this project is Digital simulation of Asymmetrical pulse width modulated (APWM) full-bridge converter. The APWM full-bridge converter uses soft switching, which means Zero Voltage Switching (ZVS) and Zero Current Switching (ZCS) .To achieve ZVS turn-on of power switches of primary side and to minimize circulating current loss, APWM full-bridge converter uses full-bridge topology and asymmetric control scheme. Zero Current Switching (ZCS) turn-off is achieved by forming resonant circuit, which consists of leakage inductance of the transformer and blocking capacitor, Thus reverse recovery problem of output diode is eliminated. In addition, voltage stresses of the power switches are clamped to the input voltage. These characteristics of APWM full-bridge converter plays vital role to minimize power losses.
