Abstract
An electrical power converter comprises an inverter with semiconductor switches, a resonant circuit coupled with the inverter, and a controller for switching the semiconductor switches of the inverter to switching states. The controller is adapted for periodically switching the inverter between switching states, such that a periodic resonant current is generated in the resonant circuit, for synchronizing switching events of the switching states with the periodic resonant current, such that a switching state is applied to the inverter at a time point associated with a specific periodic point of the periodic resonant current, and for applying the switching states such that an overall power feed backward from the resonant circuit to an input of the inverter is balanced with an overall power feed forward from the input of the inverter to the resonant circuit.
