摘要
针对单相全桥逆变器主电路中大功率MOSFET开关频率不能太高的要求,分析了双极性SPWM的调制原理,利用AVR微控制器ATmega16A-pu特性,实现了双极性SPWM分段同步调制方式。在此基础上开发了太阳能逆变器,实验表明,该样机在满足逆变器开关频率条件下,输出波形稳定、失真小。
The single-phase full-bridge inverter main circuit for normal operation under high-power MOSFET＇s requests which switching frequency is not too large,this paper analysis the modulation way principle of bipolar SPWM,utilizes the AVR micro controller ATmega16A-pu＇s characteristics to achieve bipolar SPWM segmentation synchronization modulation method,On this basis,developed a solar inverter,
