Abstract: A power transforming apparatus implements a transformation of an energy signal and comprises a control unit, a pulse width modulation (PWM) unit, a transformation unit, and a slope compensation unit. The control unit outputs a target power signal. The PWM unit is coupled with the control unit and generates a switch signal. The transformation unit is coupled with the PWM unit, and implements a power transforming of the energy signal to output an energy transformation signal according to the switch signal. The slope compensation unit is coupled with the control unit and the PWM unit, and implements a slope compensation, according to the target power signal and a feedback signal, to output a compensation signal to the PWM unit. The switch signal is generated according to the target power signal and the compensation signal.
