Abstract

This paper mainly discussed how to generate three-phase sine wave by ATmega128A single chip microcomputer. The paper describes the principle of sine pulse width modulation and pulse width algorithm of SPWM wave in detail, briefly introduces the structure and the function of ATmega128A microcontroller, and describes the functional modules used in the lab in detail. The hardware part analyses several modules of the principle diagram of the circuit boards, describes the process of drawing PCB diagram and the design of the second order filter circuit. The software part is designed in detail based on the previous theory.
