Abstract (en)
[origin: WO2019000108A1] A microwave oven comprises a microwave generator (8) having several semiconductor switches (T1 - T6) driven by a driver circuit (14). Power for the driver circuit (14) is fed through a series of safety switches (S1 - S3) mechanically coupled to the door (2) of the oven. This allows using extra-low-voltage and low-current switches while still providing a reliable means for switching off the oven when its door (2) is being opened.
