Abstract
There is provided an AC/DC two-way switch connected between an AC power source or a DC power source and a load to control a power supply to the load. The AC/DC two-way switch includes: a bi-directional semiconductor switch element having a transistor structure connected in series between a power source and the load; a rectifying unit connected in parallel between the first input terminal and a second input terminal; a power source unit for converting an output voltage from the rectifying unit into a stable voltage; and a controller for controlling an entire operation of the AC/DC two-way switch. The AC/DC two-way switch further includes a driving unit for turning on the bi-directional semiconductor switch element in response to a control signal.
