Abstract:
A main control circuit (11) for driving a motor is configured so as to have: a Pch FET (T11), which is provided in series with a diode (D1), and the source (S) of which is connected to a secondary-side contact (MC2) of a main contactor (MC) while the drain (D) is connected to the anode (A) of the diode (D1); and a gate voltage generation circuit (12) for the Pch FET (T11). The gate voltage generation circuit is formed so as to have a first resistor (R11), one end (R11a) of which is connected to the source (S) of the Pch FET (T11), and the other end (R11b) of which is connected to the gate (G) of the Pch FET (T11), and a second resistor (R12), one end (R12a) of which is connected to the gate (G) of the Pch FET (T11) and the other end (R12b) of which is connected to the negative-electrode-side line (L2) of a battery.
