Air conditioner drive power supply testing system based on single chip microcomputer control

Abstract

The invention discloses an air conditioner drive power supply testing system based on single chip microcomputer control. The air conditioner drive power supply testing system comprises an input EMC, a rectifier module, a filter module, an inversion module, a frequency conversion module and an output EMC which are sequentially connected; the input EMC and the output EMC are connected to the input end of a single chip microcomputer through an input voltage detection module and an output voltage detection module respectively; the single chip microcomputer achieves interaction communication with an upper computer through an RS485 interface. According to the system, an electric signal is subjected to a series of processing and then output to be used by an air conditioner, and the reliability and the stability of air conditioner power supply are improved; the air conditioner running speed is regulated and controlled through the frequency conversion module, and therefore the automation degree and the stability degree of speed regulation of the air conditioner are increased; an input voltage signal and an output voltage signal are collected by the input voltage detection module and the output voltage detection module respectively, and therefore the stability of a power supply is conveniently monitored to master the working state of the power supply; monitor data of the single chip microcomputer is acquired by the upper computer through the RS485 interface in real time.
