Abstract
A common mode reactor between a DC converter and an AC converter to reduce common mode voltage from current source drives. Smoothing reactors are also placed in the DC current path. Additionally, a combined DC smoothing inductor and common mode reactor can be built on a common core. The single core can be a three legged core having two coils.
