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