In an embodiment, a power converter system is provided for AC voltage regulation. The power converter system receives an AC input voltage at an input terminal and provides an AC output voltage to a load at an output terminal. A main bi-directional switch is coupled between the input terminal and the output terminal. The main bi-directional switch is operable to control the provision of the AC output voltage. A reactive current flows through the main bi-directional switch if the load is reactive. An auxiliary bi-directional switch is coupled to the output terminal. The auxiliary bi-directional switch is operable to circulate the reactive current due to the reactive load, thereby reducing any voltage spikes in the power converter system.
