<p>A system includes a power source 12 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, load, and a midpoint line; an active rectifier 16 that converts AC power from the power source to DC power for the dual-DC bus; and an impedance circuit 22 connected between the midpoint of the dual-DC bus and the system ground that provides impedance for third harmonic common-mode current.</p> |
