An apparatus for driving electromagnetic wave shielded heating wire using bedclothes is provided to accurately control a temperature in real time by attaching an insulation element to a driving device. An apparatus for driving an electromagnetic shielded heating wire using bedclothes includes a heat generating unit(C), a safety circuit unit(A), a potential check and contact inverting unit(B), a temperature sensing and driving unit(H), a short-circuit detecting circuit unit(K), a temperature setting unit(G), a micro-controller, a reference voltage generating unit, an operation/standby switch, and a display unit. The heat generating unit is equipped with a heater wire and a shield wire formed outside the heater wire to generate heat when power is supplied. The safety circuit unit automatically breaks power supply when an overvoltage occurs in the commercial power. The reference voltage generating unit supplies a reference voltage used as a set value to the micro-controller. |
