Abstract:
A ripple suppression circuit configured to suppress a current ripple provided to a load by a DC converter, can include: a ripple voltage sampling circuit coupled to output terminals of the DC converter, where the ripple voltage sampling circuit is configured to generate a ripple reference voltage that represents a ripple voltage of an output voltage of the DC converter; and a voltage regulation circuit coupled to the load and the ripple voltage sampling circuit, where the voltage regulation circuit is controllable by the ripple reference voltage such that a voltage across the voltage regulation circuit is consistent with the ripple voltage.

Claim (Index 7):
The ripple suppression circuit of  claim 6 , wherein one terminal of said sampling resistor is coupled between a positive output terminal of said voltage supply circuit, and said removing circuit comprises:\n a) a second error amplifier having a first input terminal configured to receive a DC reference voltage, and a second input terminal coupled to said sampling resistor; b) a first compensation circuit coupled between an output terminal of said second error amplifier and ground, wherein said first compensation circuit is configured to compensate an output signal of said second error amplifier; and c) a third error amplifier having a first input terminal coupled to ground, a second input terminal coupled to said output terminal of said second error amplifier, and an output terminal coupled to said sampling resistor.
