Abstract: A converter assembly and method are provided. The converter assembly includes a galvanic isolation device, first switching devices, and second switching devices. The switching devices are conductively coupled with each other and with opposite sides of the isolation device. The first switching devices control conduction of an input voltage, and the second switching devices control conduction of electric power. The first switching devices are configured to switch between an open state and a closed state at frequencies that are faster than frequencies at which the second switching devices switch between the open state and the closed state to control a shape of a waveform of the electric power.
