マイクロ波加熱装置。 A solid state relay that turns on and off the anode circuit of the magnetron is compared with a counter, and the count number of the counter is compared with a set value, and when the count number is greater than the set value, the solid state relay is turned off and the count number is equal to the set value. a comparator that turns on the solid stay relay when the solid stay relay is smaller than , a digital input section that inputs the set value to the comparator, a pulse generator that drives the counter, and a pulse generator that drives the counter and the a reset pulse generator for resetting a comparator, and controlling the microwave output of the magnetron by changing the on/off duty of the solid state relay according to the set value of the comparator.
