Performance evaluations on an active voltage-clamping self-excited zero voltage soft switching DC-DC converter for consumer magnetron drive

摘要

This paper presents a low cost active voltage clamping high side switch self-excited using IGBTs quasi-resonant DC-DC converter for magnetron drive in order to implement a simple and low cost gate drive circuit. In Addition, the particular pulse modulation pattern control inverter operating frequency in order to improve line current distortion and power factor in utility AC side are illustrated and evaluated in this paper.
