    摘要: A zero-phase current is outputted by detecting a ground-fault current with a zero-phase-sequence current transformer. A circuit having an open collector output operates when the voltage of the zero-phase current exceeds a positive side threshold value or it falls below a negative side threshold value to discharge a capacitor. When the inter-plate voltage of the capacitor falls below a threshold value voltage, a controlling means detects electric leakage to transmit that to a control unit of an air conditioner.

    摘要: A connecting member such as a terminal base is used, which allows a printed circuit board unit in which circuit elements such as a power module are mounted on a printed circuit board to be rated at higher current as compared to a conventional printed circuit board unit; and therefore an increase in size of the unit can be reduced or prevented with a simple configuration of connection sections. The connecting member of an electrical circuit connects the circuit element of the electrical circuit including the printed circuit board, to an electrical wire. The connecting member includes a terminal connecting section to be directly connected to terminal pins of the circuit element; a wire connecting section to be connected to the electrical wire; and attachment sections for attaching the connecting member to the printed circuit board.

    摘要: A reverse recovery current prevention device includes a full wave rectifier having a plurality of diodes, first and second diodes, a switch part and a switch control unit. The full wave rectifier rectifies a power source voltage from an alternating current power source inputted into first and second input terminals. The first and second diodes have anode terminals connected to the first and second input terminals, respectively. The switch part opens or shorts an electrical circuit between a negative-side output terminal of the full wave rectifier and each cathode terminal of the first and second diodes. The switch control unit prohibits the switch part from shorting the electrical circuit between the negative-side output terminal and each of the cathode terminals when a voltage between the negative-side output terminal and each of the cathode terminals is at or above a threshold.
