Abstract
A power converter and a method of converting power are provided. The power converter includes a resonant converting circuit and a control circuit. The resonant converting circuit converts an input power into an output power, and provides the output power to a load. The control circuit receives a feedback signal corresponding to the output power and the load, and outputs a driving signal according to the feedback signal to drive the resonant converting circuit. The control circuit selectively adjusts a duty period and an operating frequency of the driving signal according to a power required by the load.
Claims22
A power converter comprising:
- a resonant converting circuit which converts an input power into an output power, and provides the output power to a load;
