Introduction of an Auxiliary Resonant Commutated Pole (ARCP) Intelligent Power Module

Posted on 19 June 2020

      The ARCP half-bridge topology developed by alpitronic has implemented “soft switching” on power conversion systems. New with the topology is the absolute zero voltage switching of the half-bridge main switches, wherein the voltage swing is performed by an auxiliary resonant circuit. The resonant circuit generates an absolute zero voltage across the main [...]
