Abstract
A multilevel rectifier includes an input lead, a switching module, and a multilevel direct current (DC) link. The switching module includes a plurality of switch devices connected to the input lead. The multilevel DC link includes a positive lead, a midpoint lead, and a negative lead. each connected to the switching module. The plurality of switching module switch devices are operatively connected between the input lead and the DC link to provide a greater number of output voltage levels than the number of leads in the DC link with unidirectional power flow capability.
