Abstract: A novel circuit topology with soft switching by utilizing magnetizing inductance, leakage inductance and distributed inductance is presented. The critical factors affecting the realization of high-power soft switching are discussed. The current-injection phase-shifting technique is introduced into the research of high-power soft-switching converter successfully. A novel high-power welding converter with full mage soft switching is produced.

Key words: Current-injection phase-shifted control, High power soft-switched, Magnetizing inductance
