Abstract
A dc link module for a power circuit includes a first connector for connecting to a first power conversion circuit, a second connector for connecting to a second power conversion circuit, wherein the second power conversion circuit is connected to a load circuit arranged to at least intermittently operate as a power source to the power circuit, at least one dc link capacitors arranged between said first connector and said second connector for processing a voltage signal received at said first connector or said second connector, and at least one voltage compensation circuits arranged between said first connector and said second connector, said one or more voltage compensation circuits arranged to generate a voltage signal to compensate an ac ripple component in a dc voltage signal appearing across the at least one dc link capacitor.
