Abstract
AC to DC power electronic converter circuitry includes isolated converter circuitry and control circuitry coupled to the isolated converter circuitry. The isolated converter circuitry includes one or more wide bandgap switching components. The control circuitry is configured to drive at least one of the wide bandgap switching components such that the power electronic converter circuitry is configured to generate a DC output with an output power greater than 100W at an efficiency greater than 92%. Using wide bandgap components in the isolated converter circuitry allows the power electronic converter circuitry to achieve a high efficiency and high power density.
