Abstract
A power conversion circuit comprises an AC source, a power conversion unit, a filter inductor unit and a common mode noise suppression circuit. The power conversion unit has DC terminals and AC terminals. The filter inductor unit has first and second terminals, being respectively connected to the AC source and the AC terminals of the power conversion unit. The common mode noise suppression circuit has a capacitive impedance network with first and second terminals, and an impedance balancing network with first and second terminals. The second terminals of the capacitive impedance network are connected to the first terminals of the impedance balancing network, the first terminals of the capacitive impedance network are connected to the first terminals of the filter inductor unit, and the second terminals of the impedance balancing network are connected to the DC terminals of the power conversion unit.
