Title: RESONANT POWER CONVERTER COMPRISING RIPPLE SUPPRESSION CIRCUIT
Abstract:
The present invention relates to a power converter assembly comprising a resonant power converter configured for converting a rectified input voltage into a DC output voltage and a ripple compensation circuit. The ripple compensation circuit is configured to estimating and synthesizing a ripple compensation signal at least partly based on a ripple component of the rectified input voltage and superimposing, directly or indirectly, the ripple compensation signal onto the DC output voltage of the assembly to suppress a ripple voltage component of the DC output voltage.
