Abstract

This design mainly uses the equivalent area algorithm to calculate the inverter to generate the SPWM waveform, and keep the output waveform undistorted. At the same time, the ADC0809 is controlled by the single-chip microcomputer to collect and output the voltage value and display it on the digital tube. The main requirements of the design are low cost, small size, no need to adjust external components, and simple interface. The generation of SPWM is generated by the singlechip ATMEGA8 according to the algorithm. After isolation, drive and amplify, and finally filter the output, the required sine waveform was obtained. This subject is very practical and is used in many fields, such as: used in AC motor speed control systems, ships, aerospace, post and telecommunications, military equipment, transportation facilities, instrumentation, industrial equipment.
