ABSTRACT:
A safety circuit includes a thermal fuse electrically connected in a main current path so that an electric current flowing in the main current path flows through the thermal fuse; a switching element electrically connected to the thermal fuse to cause the thermal fuse to open and interrupt the electric current flowing in the main current path when the switching element is turned on; a microcontroller electrically connected to the switching element and the main current path to turn on the switching element when an overcurrent flows in the main current path; and a noise removing unit electrically connecting the microcontroller to the switching element.
