Abstract
A power inverter includes two input terminals, two output terminals and a resonant converter that includes a high frequency transformer having a primary winding and a secondary winding, at least one high frequency switched semiconductor power switch that connects one end of the primary winding of the high frequency transformer to one of the input terminals to provide a current path through the primary winding to the other one of the input terminals. The power inverter further includes a resonant series circuit having an inductance and a capacitance, and a high frequency rectifier that rectifies a current through the secondary winding, two output lines, and an output converter connected between the output lines of the high frequency rectifier and the two output terminals.
