Stability Improvement of High Power Factor Converters by Switched Capacitors |
| |
| Abstract: | The stability is analyzed for a closed loop single stage power factor correction(PFC) integrated converter with a discontinuous conduction mode(DCM) input part. Obtained is the condition for which the output voltage can be maintained within the desired range by pulse width modulation(PWM).The input voltage range and the load current range are also discussed. A PFC DCM boost buck converter is investigated with results verified by experiments. |
