摘要
本文研究一种电压电流双闭环瞬时值控制的单相 SPWM 变频电源,分析了闭环参数对系统的影响,给出了参数设计的依据和方法。所研制的 SPWM 变频电源输出波形质量好,频率可在较宽的范围内变化,实验结果证明了该设计的可行性。
This paper researched a single-phase SPWM inverter instantaneonsly controlled by the voltage and current loops.analyzed the effect of closed-loop parameters to system.and given the rules and method s of parameters design.A SPWM inverter is designed has good quality output waveforms and wide range frequency.The experimental results show the feasibility of the design.
