Compensating ripple on pulse with modular outputs

摘要

A ripple compensation apparatus comprises a ripple detection units 204 to detect a ripple on a dual DC a waveform generation unit 210 to generate a modulated waveforrn based on a base wavefonn and the detected ripple, and a multiphase control signal generation unit 18 to receive the modulated waveform and to generate at least one pulse width modulated control signal based on the modulated waveform,
