查询词典 reverse current

In this condition, the parallel transformer can exhibit nearly zero impedance to harmonic current and very high primary self-impedance to fundamental current and thus lead harmonic current in power systems to flow into the transformer branch. With a step-down transformer, the power semiconductor switches of the active power filter are always worked in relatively low voltage, which ensure the security and reliability of the active filtering device.
