The electric fire stove is a novel stove which utilizes the characteristics of plasma, uses high-voltage electricity to puncture air to form thermal plasma, converts electric energy into heat energy, finally obtains thermal plasma beams with ideal functions, and generates the thermal plasma beams with similar flame characteristics to heat a pot for cooking. Because the electric energy is used as direct energy input, and the commercial power needs to be boosted to a high voltage of 10KV for generating plasma beams, a transformer needs to be arranged inside the electric fire stove for voltage boosting.

The transformer structure in the existing electric fire stove has the following defects:
