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 16):
A method for controlling an AC ripple from a switched mode power electronic converter connected to a DC link of a host DC voltage system, comprising the steps of:\n providing a two terminal device across the DC link; causing the two terminal device to emulate the AC ripple and to reflect the AC ripple in the impedance it presents to the DC link so as to reduce the AC ripple; causing the impedance to be presented in such a way as to not alter the DC link; controlling the two terminal device based on the measurement of the DC link.
