The present invention relates to a temperature controlling apparatus for insulation bedclothes. More particularly, the present invention relates to an AC control-typed temperature controlling apparatus having a fault diagnosis function for insulation bedclothes, which is synchronized with an AC sine wave signal to accurately analyze a detection position and a distorsion for a temperature signal waveform and a heater current waveform, more accurately controls the temperature of a heating line, has a fault diagnosis function of the abnormal operation of a heater power controller or the short circuit of the temperature detection line of the heater, and prevents the generation of a fire due to the failure of the heater power controller and a micom. The temperature controlling apparatus includes an AC synchronization detection part, an AC power blocking part, and a heating circuit part. |
