Abstract :
This paper describes the effective protection circuit in the microwave oven using the topology of quasi-class E resonant inverter system. We present what is the most dangerous input condition, how to solve that problem and what is the most effective method to solve that problem to increase the reliability. We suggest the most effective method of protection to be checking the current as soon as possible without any noise signal, and to stop the inverter operating for protection. Also, we show the test results of 1300 Watt inverter microwave oven
