| Abstract: | At present, the high power plasma technology is widely used . A novel circuit topology with soft switching by utilizing magnetizing inductance, leakage inductance and distributed inductance is presented. This topology is applied to the realization of high power plasma converter. The current injection phase shifted technique is introduced into the research of soft switching plasma converter successfully. The magnetic biasing of transformer and the protection of switching parts are solved.A novel high power plasma converter with full range soft switching is produced. |
