Abstract

PURPOSE:To control the rising rate of overvoltage and that of voltage at the time of switching for chopper devices by dividing flywheel diodes into the number of pieces corresponding to the chopper devices. CONSTITUTION:Flywheel diodes FWD1, FWD2 are arranged by corresponding to each chopper device GT1, GT2 and current balancers L<1>, L2 are also adrranged. In this way, the currents at the time of turning off the chopper devices GT1, GT2 pass through the flywheel diodes FWD1, FWD2 and become field currents IF1, IF2 to charge a filter capacitor CF. And then, the applied overvoltages in the chopper devices GT1, GT2 become the same level as the voltage in the filter capacitor CF.
