A thermoelectric assembly for powering one or more electromagnetic valves of a cooking appliance. According to one embodiment the assembly includes a main current circuit that includes a thermocouple, a cable configured for electrically connecting the thermocouple with an electromagnetic valve, and a transistor connected to the cable and configured for de-energizing the electromagnetic valve. The main current circuit also includes a connection module that includes a power supply connected to the transistor, the power supply having input terminals configured for being connected to an external energy source, a rectifier, and a resistive block connected between one of the input terminals and the rectifier, the resistive block being configured for minimizing the current circulating through the power supply to a value equivalent to the galvanic isolation.
