The operation state and connection mond of Sinewave Pulse Width Modulation(SPWM) Inverter directly affect the output voltage waveform, circuit efficiency, Voltage convert ratio and circuit connection complexity etc. Not taking some practical situations(load property and three phase output circuit connection etc.) into account, some domestic theoretical nnalyses of output waveforms of inverters are much different from the output waveforms of practical circuits. Blind using the conclusions of those analyses may lead to mistakes. In this paper the invelter is discussed experimently and analytically in different combinations of different loads(resistance, motor), different operation states(monopole, bipole), and different circuit connections(Yo, Y, delta), and some conclusions are reached.

在对正弦波(s)脉冲宽度调制(PWM)逆变器的研究与应用中,选择怎样的运行状态与接线方式,关系到输出电压波形质量、电路的效率与电压转换率以及电路结构的复杂程度等等。在国内,通常对逆变器输出波形的理论分析,由于没有考虑一些实际情况(例如负载性质及三相输出电路的接法不同对输出波形的影响等),与许多实用电路有很大的差别。如不注意具体情况不同而盲目套用那些分析结果,将可能造成错误。本文通过对逆变器在不同负载(电阻、电动机)、不同运行状态(单极性与双极性)、不同接线方式(Y_0、Y、△)的各种组合条件下的试验和分析,得出了一些结论,供从事SPWM逆变器研究的同行们参考。
