一种由单片机控制的高性能正弦波电源的研究

Study of the high capability sine-wave power control based on thesingle-chip

本文介绍了基于SPWM控制的逆变电源的设计。SPWM脉宽调制技术应用于逆变电源的控制中,其原理简单,控制及调节性好,输出电压稳定等特点。整个系统完全由单片机控制,采用IR2132可以实现对功率管的驱动和保护,直流升压及反馈由SG-3525控制。经试验表明:逆变电源输出波形失真小,动态特性好,可靠性高。

The design of the inverter based on SPWM is introduced. The SPWM was applied to realize the power supply control, which makes the power supply having the characters of simple principle, good control and regulation performances, and stabilize the out voltage etc. Used IR2132 to drive and protect power transistor. DC-DC boost unit by SG-3525 controlled. By testing, this system has the merits of high output-stability, good dynamic characteristic and high dependability.
