Microwave Oven용 마그네트론의 전력제어에 관한 연구

This paper describes a output power control of magnetron for microwave oven. Magnetron is used extensively in household microwave oven and industrial microwave heating devices. it is operated by 3000[V] -5000[V] dc high voltage. Power supply for driving magnetron is consisted of a bridge rectifier. HB(half bridge) inverter. full wave rectifier and gate drive circuit. In proposed system. we confirm that line input power can be controlled extensively and linearly to 24.56(%) by change of duty ratio of inverter through a experiment.
