Embodiments of the invention provide methods and apparatuses for concurrently eliminating or substantially reducing two or more switching losses in an inverter switching circuit. Embodiments of the invention concurrently reduce multiple types of switching losses under hard switching mode and soft switching mode for active switching devices and diodes. In one embodiment of the invention, the voltage across a switching device is substantially reduced during switch turn-off and/or turn-on time, and also maintained at a substantially reduced level throughout some or all of the tail current loss time of the switching device. Other methods and apparatuses are also described.
Dans des modes de réalisation, l'invention concerne des procédés et des appareils permettant concurremment d'éliminer ou de limiter sensiblement deux ou plusieurs pertes de commutation dans un circuit de commutation d'inverseur. Dans d'autres modes de réalisation, l'invention permet de limiter concurremment des types multiples de pertes de commutation en mode commutation dure et en mode commutation douce pour des dispositifs de commutation et des diodes. Dans un mode de réalisation de l'invention, la tension sur un dispositif de commutation est sensiblement limitée pendant la durée d'activation et/ou de désactivation d'une commutation, et est maintenue à un niveau sensiblement réduit pendant la durée partielle ou totale de perte de courant de queue du dispositif de commutation. L'invention concerne également d'autres procédés et appareils.
