A system includes a power source that provides alternating current (AC) power and is connected to system ground; a dual-DC bus that provides direct current (DC) power to a load, and comprises a positive line, a negative line, and a midpoint line; an active rectifier that converts AC power from the power source to DC power for the dual-DC bus; and an impedance circuit connected between the midpoint of the dual-DC bus and the system ground that provides impedance for third harmonic common-mode current. |
