Abstract
A method includes controlling the cyclo-converter 7 in coordination with controlling a coupled HF inverter 3. The controlling of the cyclo-converter 7 provides at least a first freewheeling FW period in the cyclo-converter for each cycle of the HF inverter 3. The controlling of the HF inverter provides a freewheeling period in the HF inverter 3 each time the first freewheeling period is provided in the cyclo-converter.
