摘要
An apparatus is provided for bypassing a load current going through an AC-AC series voltage regulator under over-current condition, comprising: an AC-AC invertor; an AC semiconductor bypass switch; and a bypass control. The AC-AC invertor and the AC semiconductor bypass switch are connected in parallel. The bypass control is configured to detect a load current signal, an input voltage of the AC-AC series voltage regulator and an output voltage of the AC-AC series voltage regulator and to control the AC semiconductor bypass switch's switching such that the load current under overcurrent condition is shared between the AC-AC invertor and the AC semiconductor bypass switch.
