Zusammenfassung:The present invention relates to an electric heater and a control method of the electric heater. The electric heater according to one embodiment of the present invention comprises: a heating element that dissipates heat according to a voltage being supplied from an external power source; a switch disposed between the external power source and the heating element to adjust a supply voltage from the external power source to the heating element; a voltage detection part that detects a supply voltage value for which is the voltage value supplied from the external power source; and a control part that compares the supply voltage value with a preset reference voltage value, and adjusts a turn-on time per cycle of the switch based on a comparison result. Therefore, the present invention is capable of having an advantage for which the same output power can be outputted even if the supply voltage value is changed. 본 발명은 전기 히터 및 전기 히터의 제어 방법에 관한 것이다. 본 발명의 일 실시예에 따른 전기 히터는 외부 전원으로부터 전압이 공급됨에 따라 열을 발산하는 발열체, 외부 전원과 발열체의 사이에 배치되어 외부 전원으로부터 발열체로의 전압 공급을 조절하는 스위치, 외부 전원으로부터 공급되는 전압값인 공급 전압값을 감지하는 전압 감지부 및 공급 전압값과 미리 설정된 기준 전압값을 비교하고, 비교 결과에 기초하여 스위치의 주기 당 턴-온 시간을 조절하는 제어부를 포함한다.
