• High - frequency link power converters are receiving increasing attention . when the input frequency of ac - ac converter is quite high , such as 20khz or above , in order to make sure the converter switching action is restricted to the zero crossing point of the link voltage , the switching cycle becomes discrete pulse spectrums , however , the conventional pwm converters are ruled out because they would fail either to the efficiency or the low - distortion criteria
  当交-交变频器的输入频率非常高，通常为20khz时，为了在零电压条件下实现逆变器开关管的通断，变换器的开关时刻必须选择在高频交流电压脉冲为零时，这意味着变换器开关时刻在时间轴上成为不连续的点，而常规的硬开关pwm变换器是将开关时刻选择在任意时刻。
• The unsteady input commercial frequency sinusoidal voltage with high harmonic is modulated into bi - polarity three - state high frequency ac volage by the input cycloconverter , bi - polarity three - state high frequency ac volage is demodulated into uni - polarity three - state spwm wave by the output cycloconverter , and the uni - polarity three - state spwm wave is filter into steady commercial frequency sinusoidal voltage with low harmonic
  输入周波变换器将输入不稳定劣质的工频正弦交流电压调制成双极性三态的高频交流电压波，输出周波变换器将此高频交流电压波解调成单极性三态spwm波，经输出滤波后得到稳定优质的工频正弦交流电压。
