Ac variable frequency speed control system performance index has reached pletely and dc speed parable degree, showed the good performance that the application of the more widely. This system USES 24v dc power supply, through the inverter circuit, the dc into three phase alternating current , and then control three phase asynchronous motor Use DSP output SPWM waveform, variable frequency speed regulation system as the input of the control signal to control the entire system, realize frequency and the number of the unction of the controller. Meanwhile,using LCD,led and eeprom asa display and saving.
