  • Power supply control circuit and cooking device
    Patent number: 6680463
    Abstract: In the power supply control circuit, interposed between the power lines 1a and 1b is a serial circuit 21 constructed by connecting in series a radio interference suppression capacitor 2 for suppressing radio interference and a power supply holding switch 4. A node of the radio interference suppression capacitor 2 and the power supply holding switch 4 is connected via an auxiliary power line 1d to a primary side terminal 7a of a stepdown transformer 7, and another primary side terminal 7b of the stepdown transformer 7 is connected to a power line 1b. With the power supply control circuit, reduction of electric power consumption can be realized using a power supply holding switch with a small capacity.
