Abstract
The present invention consists in connecting an auxiliary D.C. voltage source to a series-connected assembly constructed of electronic switches, whereby even when the electronic switches in the series-connected assembly have unequal switching rates, any overvoltage is not applied to the electronic switches and any power loss ascribable to the overvoltage is prevented.
