Abstract:
In many power electronics systems, there is an intermediate DC-link stage for facilitating the power processing of different sources to their loads. A device called a plug-and-play ripple pacifier (RP) directly plugged into the DC-link, and actively removes undesired DC-link ripple, thereby eliminating the reliance on electrolytes capacitors for stabilizing the system and remove ripple. Importantly, the use of this device is non-invasive to the operation of its host systems, and requires no modification of existing hardware. It is suitable for the protection of DC utilities/systems and can also be used as a direct replacement of ripple-canceling E-Caps in power converters device.

Claim (Index 10):
A DC voltage system that provides DC voltage to DC utilities and systems, comprising:\n a power converter for providing the DC voltage to a DC link to which the DC utilities and systems are connected; and a ripple pacifier connected across the DC link, said ripple pacifier presenting variable impedance to the DC link so as to reduce an AC ripple in the DC link, said ripple pacifier relying only on the DC voltage for control and not adversely affecting the DC link.
