Abstract:
1. A power transforming apparatus implementing a transformation of an energy signal, the power transforming apparatus comprising: a control unit outputting a target power signal; a pulse width modulation (PWM) unit coupled with the control unit and generating a switch signal; a transformation unit coupled with the PWM unit, and implementing a power transforming of the energy signal to output an energy transformation signal according to the switch signal; and a slope compensation unit coupled with the control unit and the PWM unit, and implementing a slope compensation, according to the target power signal and a feedback signal, to output a compensation signal to the PWM unit, wherein the switch signal is generated according to the target power signal and the compensation signal, wherein the control unit further outputs a descending tendency signal to the slope compensation unit, and the slope compensation unit processes the target power signal to generate a ramp signal according to the descending tendency signal, and outputs the compensation signal according to the ramp signal and the feedback signal.
