摘要
以通用逆变电源为设计目标,采用SPWM脉宽调制作为控制核心,对单相逆变器进行稳压调节与仿真。建立了逆变电路仿真模型,通过输出电压瞬时值进行闭环PID控制,输出电压可在50～220V内调节,适应于一般性负载。
Aim to general inverter power supply design, using SPWM pulse width modulation as control core, to regulate and simulat the single- phase inverter voltage. The inverter circuit simulation model is established, and the output voltage instantaneous value is controlled by closed loop PID, the output voltage can be adjusted within the 50-220V, which is suitable for general load.
