Abstract
System and methods for power conversion are provided. Aspects include a first switching module comprising a first set of switches, wherein the first set of switches comprise wide-bandgap devices having a first bandgap, a second switching module comprising a second set of switches, wherein the second set of switches comprise semiconductor devices having a second bandgap, and wherein the first bandgap is larger than the second bandgap, an alternating current (AC) power source connected to the first switching module and the second switching module, a first capacitor bank, a second capacitor bank, and a controller configured to operate the first switching module and the second switching module to create a first direct current (DC) voltage across the first capacitor bank and a second direct current (DC) voltage across the second capacitor bank.
