Abstract:
An anti-power environment suppression circuit includes: a power input terminal configured to receive an alternating current input from an external power source; a power output terminal configured to output the alternating current that has undergone anti-interference processing; a live wire, a neutral wire and a ground wire that are coupled in parallel between the power input terminal and the power output terminal; and a common-mode suppression sub-circuit coupled in the ground wire. The common-mode suppression sub-circuit is further coupled to the live wire and the neutral wire, and the common-mode suppression sub-circuit is configured to suppress common-mode interference between the ground wire and the live wire, and suppress common-mode interference between the ground wire and the neutral wire, so as to perform the anti-interference processing on the input alternating current.
