Activation circuit and energy storage power supply thereof

Abstract

The embodiment of the utility model discloses an activation circuit and an energy storage power supply thereof. The activation circuit comprises a power supply input end, a voltage conversion module and a signal generation module, wherein the power supply input end comprises a first live wire end, a second live wire end and a zero wire end; the voltage conversion module is configured to convert the received single-phase double-live-wire alternating current into a first path of alternating current from the first live wire end to the zero line end and a second path of alternating current from the second live wire end to the zero line end in a capacitive voltage division mode when the power input end receives the single-phase double-live-wire alternating current. The signal generation module is configured to generate an activation signal in response to the first path of alternating current or the second path of alternating current so as to activate the energy storage power supply. According to the embodiment of the utility model, automatic activation of the energy storage power supply can be realized through a small number of resistance-capacitance elements under the condition of single-phase double-live-wire alternating current input, and the compatibility of the activation circuit is improved.
