Abstract: According to various embodiments, an electronic device comprises: an input terminal configured to receive alternating current (AC) power from an external source; an output terminal configured to output the AC power; a solid state relay (SSR) configured to selectively connect the input terminal and the output terminal, the SSR comprising a zero-crossing detector, wherein the zero-crossing detector is configured to detect a zero voltage of a voltage associated with at least one voltage of the input terminal and/or the output terminal; a bypass circuit connected in parallel to the SSR and configured to selectively connect the input terminal and the output terminal; and a controller, wherein the controller is configured to: obtain a power supply interruption command while supplying the AC power to the output terminal via the bypass circuit, turn on the SSR, based on the obtaining of the power supply interruption command, turn off the bypass circuit, based on the lapse of a first period after turning on the SSR, and turn off the SSR, based on the lapse of a second period after turning off the bypass circuit, and wherein when the SSR is on, the SSR is configured to release a connection between the input terminal and the output terminal when the zero-crossing detector detects substantially 0V at the input terminal.
