(EN) An electric device is provided which can reduce risk of malfunction. This electric device is provided with a motor (32), an inverter circuit (30) which has switching elements (S1-S6) and which drives the motor (32), and a charge pump circuit (22) which generates the drive voltage of the switching elements (S1-S6). A discharge circuit (a discharge resistor R and a capacitor C1) is provided between a power line to which a drive voltage (VM) of the motor (32) is supplied and an output terminal (a VGT terminal) of the charge pump circuit (22). Energy of the surge voltage (Vs) generated in a parasitic inductance (Ls) when the switching elements (S4-S6) are turned off is absorbed by the discharge circuit (the discharge resistor R and the capacitor C1).
(ZH) 本发明提供一种可抑制故障风险的电气机器。电气机器包括：马达(32)；逆变电路(30)，具有开关元件(S1～S6)且驱动所述马达(32)；以及电荷泵电路(22)，生成所述开关元件(S1～S6)的驱动电压。在供给所述马达(32)的驱动电压(VM)的电源线与所述电荷泵电路(22)的输出端子(VGT端子)之间设有放电电路(放电电阻R及电容器C1)。开关元件(S4～S6)关断时在寄生电感(Ls)产生的浪涌电压(Vs)的能量由放电电路(放电电阻R及电容器C1)吸收。
