A method of pulse-width control of the high power full-bridge converter with widely varied supply voltage is proposed. The method is based on the carrier frequency variation and is implemented as proportional-integral controller with adjustable parameters. The proposed method allows improving dynamic characteristics of the system and limiting of maximum current commuted by transistors. The proposed control law allows receiving desired load voltage.

Keywords: full-bridge inverter, soft commutation, pulse-width control, proportional-integral controller with adjustable parameters, transformer leakage inductance
