基于单片机实现移相控制的正弦波逆变电源

Single-chip Microcomputer Based on Phase-shift Inverter

提出了一种具移相变频功能的正弦波功率信号源,该信号源利用数字移相技术,采用锁相环和单片机配合实现移相功能,并基于EPROM存储和8位单片机配合控制,生成全数字的高频高精度SPWM波来调制。

A phase-shift inverter based on a single-chip microcomputer is introduced. PLL and a single-chip microcomputer is used in this inverter to realize digital phase-shift technology. At the same time, fail digital, high frequency and high precision SPWM is produced by EPROM and the 8 bit single-chip microcomputer.
