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
當交-交變頻器的輸入頻率非常高，通常為20khz時，為了在零電壓條件下實現逆變器開關管的通斷，變換器的開關時刻必須選擇在高頻交流電壓脈沖為零時，這意味著變換器開關時刻在時間軸上成為不連續的點，而常規的硬開關pwm變換器是將開關時刻選擇在任意時刻。 -
