Problems solved by technology

[0003] However, when charging the capacitor, since the capacitor is generally a high-voltage aluminum electrolytic capacitor, there is a certain leakage current. The higher the voltage, the greater the leakage current, that is, the greater the loss. Therefore, the higher the input voltage through the power conversion device The greater the loss, and the input voltage of the power conversion device depends on the value of the external AC power supply, the input voltage of the power conversion device cannot be actively reduced

Abstract

The invention provides an air conditioner and a control device and method thereof. The device comprises a main working module and a low-power-consumption power supply control module, wherein the main working module is used for supplying power to an electricity load when the electricity load of an electric controller of the air conditioner has a power supply demand; and the low-power-consumption power supply control module is connected with the main working module and is used for outputting a voltage control signal to control the magnitude of an external alternating-current power supply when the electric controller of the air conditioner is in a standby state. By arranging the low-power-consumption power supply control module, when the electric controller is in the standby state, the voltage control signal is output to control the size of the external alternating-current power supply, a controllable alternating-current power supply is formed, and the standby loss of the electric controller is reduced, so that the seasonal energy efficiency ratio is increased when the seasonal energy efficiency of the whole machine is calculated.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and its control device and method. Background technique [0002] In the related technology, the AC power supply charges the capacitor through the rectification device after passing through the current limiting resistor to obtain a stable DC voltage, and then converts it into the low voltage required by the circuit operation through the power conversion device, and supplies the low voltage to the control circuit device, In order to make the control circuit work normally. [0003] However, when charging a capacitor, because the capacitor is generally a high-voltage aluminum electrolytic capacitor, there is a certain leakage current. The higher the voltage, the greater the leakage current, that is, the greater the loss. Therefore, the higher the input voltage through the power conversion device The loss is also greater, and the input voltage of the power...
