一种能够降低空调待机功耗的电源控制电路

为了有效降低空调的待机功耗，设计了一种旨在降低空调待机功耗的电源控制电路。该控制电路通过取样电路检测空调实际工作电流的大小，判断空调的工作状态，当检测到空调处于待机状态超过1min左右，控制电路自动切断空调插座的电源。实测证明该控制电路可以有效降低空调的待机功耗，可以做到待机功耗不大于1w。该控制电路采用光耦可控硅作为核心控制元件，控制电路中使用了红外接收器，其正常工作时不会影响空调遥控器的正常使用。

Power-supply control circuit to reduce standby power consumption of air conditioner

A power-supply control circuit was designed to reduce the standby power consumption of air conditioners.The control circuit determines the working status of an air conditioner by a sampling circuit to detect the actual operating current,and cuts off the power at socket automatically when the air conditioner is in standby mode for more than a minute or so.The actual measurement proves that the control circuit can effectively reduce the standby power consumption of air conditioner.The standby power consumption is less than 1 W when the control circuit is working.The optocoupler triac taken as a core element and the infrared receiver are used in the control circuit.The control circuit does not affect the normal use of the air conditioner′s remote controller when it is working.
