Abstract
A control circuit controls a power output module and drives a load device. The control circuit includes a conversion unit, a feed-forward unit, a feedback unit and a control unit. The conversion unit generates a driving signal according to an output signal of the power output module for driving the load device. The feed-forward unit generates a duty cycle reference signal according to the output signal. The feedback unit generates a feedback signal according to the driving signal. The control unit outputs a control signal to control the conversion unit according to the duty cycle reference signal and feedback signal, thereby limiting the output power of the power output module within the maximum power region. A tracking method of the maximum power is also disclosed.
