PWM逆變器的廣義軟開關

摘要：在PWM逆變器中，用緩沖網絡技術降低主開關的du/dt和di/dt，以實現近似零電流開通或零電壓關斷，從而減少了開關損耗，是一種廣義軟開關技術。 敘詞：廣義軟開關 PWM逆變器 緩沖電路 Abstract：For a PWM Inverter,a snubber circuit reduces witching losses by lowering the main switch's du/dt and di/dt to achieve nearly zero-switching(ZC turned-on and ZV turned-off)which is called a generalized soft suitching technique.
