Title:
SOFT SWITCHING INVERTER
Document Type and Number:
WIPO Patent Application WO/2015/127829
Kind Code:
A1
Abstract:
An inverter comprises a first switch coupled to an input of an output filter and a positive dc bus, a second switch coupled to the input of the output filter and a negative dc bus, a transformer coupled to a common node of the first switch and the second switch, a first freewheeling apparatus and a first soft switching switch connected in series, wherein the first soft switching switch is configured such that the first switch is of a first zero voltage transition during a turn-on process of the first switch and a second freewheeling apparatus and a second soft switching switch connected in series, wherein the second soft switching switch is configured such that the second switch is of a second zero voltage transition during a turn-on process of the second switch.
