Rectifying device protection circuit and electrical equipment

The utility model discloses a rectification device protection circuit and electrical equipment. The circuit comprises a power supply module, a protection module and a rectification device. The power supply module is used for outputting alternating current voltage when the off state is switched to the power supply state, and outputting impact current corresponding to the alternating current voltage to the protection module; in a power supply state, the AC voltage is output to the protection module; the protection module is used for absorbing impact current in a first working state; in the second working state, the AC voltage is transmitted to the rectifying device without loss; the rectifying device is used for converting the alternating-current voltage into direct-current voltage to be output. When the protection module works in the second working state, the alternating current voltage can be transmitted to the rectification device without loss, the problems that in the prior art, a thermistor is connected in
