摘要： DC 5V shared with a shaver is inputted into a step-up circuit of a cleaner from a terminal of an AC adapter. When an oscillation circuit turns on/off an FET, the voltage is stepped up by using a choke coil, and the charge is accumulated in a capacitor. By using DC 24V of the stet-up result outputted from the capacitor, an electromagnetic induction heating circuit allows an FET to turn on/off the current flowing through a coil, the blade edge of the shaver is induction-heated. In this case, by applying a trigger pulse of the oscillation circuit through an inverter to the FET, the duty factor of the step-up circuit is high, and that of the electromagnetic induction heating circuit is low.

摘要： To provide a power supply circuit which can be applied worldwide without using a high withstand voltage switching element and can supply a load device with stable power. A charging section is arranged between a turn-off capacitor and a load coil. The charging section has the anode connected to the positive terminal of a feedback coil and the cathode connected to the cathode of a zener diode. Thus, when a voltage of a commercial power supply is high, the charging section operates, the turn-off capacitor is quickly charged, an on-period of a transistor is shortened, and an excessive voltage is prevented from being applied between the drain and the source of the transistor. At the same time, an output characteristic indicating relationship between the voltage of the commercial power supply and a current flowing in the load device is permitted to be flat.

A passage is formed between the printed circuit board and the primary transformer component to provide a connecting orifice between a core space of primary transformer component and the space external to the primary transformer component.
