SYSTEM AND METHOD FOR SUPPRESSION OF PEAKING IN AN EXTERNAL LC FILTER OF A BUCK REGULATOR |
摘要 |
<p>Disclosed are systems and methods for suppressing voltage peaking in a buck regulator. In one aspect, a buck regulator comprises: a pulse-width modulator (PWM) that generates a pulsed signal; a switch operable to selectively connect the regulator to a DC power supply in response to the pulsed signal and output a pulsed output DC signal; a filter for filtering out high frequency noise from the pulsed output DC signal and generating a regulated output signal; an integrator for comparing the pulsed output DC signal with a reference voltage signal and generating an error signal for input to the PWM; a subtractor operable to subtract the reference voltage signal from the filtered output signal to generate an error feedback signal; and an adder operable to add the error feedback signal to the error signal for input to the pulse-width modulator in order to suppress voltage peaks in the filtered output signal.</p> |
