【摘要】 本文分析一种脉宽调制阶梯波逆变电路,它利用六个可控硅的不同导通次序,获得十二阶梯波,它的最低次谐波为十一次,而且它的谐波次数与导通角无关。文中导出了这一波形的阶梯高度、变压器线匝和换流元件的设计公式。更多还原

【Abstract】 In this paper, a pulse width modulation inverter circuit is analysed, in which, twelve step waveforms is obtained by means of six thyristors. the circuit is characterized with a lowest harmonic of eleventh order, whilst the harmonics bear no relation to the conduct angle of thyristors. A number of design formulars for the step height of waveform, the transformer coil and commutation components are derived.更多还原
