Duty feed forward method and apparatus for modulating a duty of a PWM signal and power converting method and power converter using the same
摘要:
The duty of a PWM signal in a power converter is extracted to feed forward to modulate the slope of a linear oscillating ramp signal or the voltage level of an error signal, so as to modulate the duty of the PWM signal, by which the transient response of the power converter and the stability of the PWM loop both are improved.
