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.
Claims9
A method, comprising:
- controlling a cyclo-converter to provide at least a first freewheeling period in the cyclo-converter for each cycle of an HF inverter;
- and
- controlling the HF inverter to provide a freewheeling period in the HF inverter each time the first freewheeling period is provided in the cyclo-converter.
A processor readable medium that contains logic modules for controlling a processor, the logic modules comprising:
- a first module controlling the processor to control a cyclo-converter to provide at least a first freewheeling period in the cyclo-converter for each cycle of an HF inverter;
- and a second module controlling the processor to control the HF inverter to provide a freewheeling period in the HF inverter each time the first freewheeling period is provided in the cyclo-converter.
A controller comprising:
- a first means for controlling a cyclo-converter to provide at least a first freewheeling period in the cyclo-converter for each cycle of an HF inverter;
- and
- a second means for controlling the HF inverter to provide a freewheeling period in the HF inverter each time the first freewheeling period is provided in the cyclo-converter.
