Reduce the standby power consumption of a microwave oven

A touch panel microwave oven which is turned off does not mean that it is not consuming electric power. Although it is turned off, it still consumes 1 to 3 W when it is plugged into an ac socket. In this design the touch panel microwave oven consumes 3 mW when it is turned off and yet plugged in. A more effective circuit design for a touch panel microwave oven is proposed to reduce the standby power consumption, which is also easy to apply to future products. This power consumption in the standby state is lower than that of others and not only simple to set up but also inexpensive¹.
