来源:[C].IEE Colloquium on Resonant Systems1995IET
摘要:Resonant link techniques allow high operating frequencies to be attained by providing instances of zero voltage or current at which the main power devices may change state. The switching losses are thus reduced and the devices may operate at higher frequencies. This is achieved b...
