Abstract
A surge current suppressing circuit is applied between an AC power and an electronic device that receives the AC power via a first AC power line and a second AC power line. The surge current suppressing circuit has a first input fuse connected to the first AC power line, and a first air-core inductor connected in series with the first input fuse on the first AC power line to suppress a surge current. Depending upon the practical applications, the surge current suppressing circuit can further have a second air-core inductor connected to the second AC power line, a capacitor connected between the two AC power lines or both.
