Thermoelectric safety assembly

A gas combustion system comprising:

• a gas burner;
• a thermocouple configured to detect a flame generated by the burner and to produce an electrical voltage in response to detecting the flame;
• an electromagnetic valve electrically coupled to the thermocouple and configured to allow a passage of gas towards the burner when the electromagnetic valve is energized by the thermocouple;
• a field-effect transistor electrically connected between the thermocouple and the electromagnetic valve and transitional between an open state and a closed state, in the open state a current generated by the thermocouple is not allowed to pass through the field-effect transistor, in the closed state the current generated by the thermocouple is allowed to pass through the field-effect transistor, the electromagnetic valve being electrically coupled to the field-effect transistor;
• and
• a voltage booster configured to power the field-effect transistor and being connected in parallel with the field-effect transistor, an output terminal of the voltage booster being arranged connected with a gate terminal of the field-effect transistor, the voltage booster being configured to boost the electrical voltage generated in the thermocouple so that the electrical voltage is sufficient to cause the field-effect transistor to assume the closed state to allow a current to flow from the thermocouple through the field-effect transistor to energize the electromagnetic valve.
