Abstract
The utility model discloses a low-power-consumption double-channel power supply energy-saving circuit. The low-power-consumption double-channel power supply energy-saving circuit is characterized by comprising a capacitance buck type power supply circuit and a controllable reactive circuit.

The circuit provided by the utility model has the advantages of small occupation space and low cost. When the circuit is working, two power supply channels are simultaneously supplying power. When the circuit is in a standby state, a unidirectional silicon controlled rectifier is controlled by a control chip to be conducted and the current in one power supply channel is made to flow back to the power grid. The standby power consumption is thus effectively reduced. The circuit thus accords with the desire of people enjoying an energy-saving environment-friendly and low-carbon-emission lifestyle.
