Abstract
A voltage converter includes a set of series connected capacitors collectively configured to provide voltage to an inverter. The voltage converter includes a switchgear including rails and switches configured to energize the capacitors with energy from the rails. The voltage converter includes interleaved inductors having respective half bridge switches configured to energize the rails. The voltage converter includes a controller configured to operate the switches of the switchgear to energize less than all of the set. The switch operation is responsive to a request to change the DC link voltage.
