发明名称 Method of controlling a thermal protection device of a power transistor, and system for implementing the method
摘要 According to the invention, the method consists in measuring the gate-source voltage of a MOS field-effect transistor (T), this voltage varying with temperature, in comparing it with a reference voltage corresponding to a given temperature, and in turning off the transistor (T) when the gate-source voltage is higher than the reference voltage. The invention applies in particular to protecting electronic power controllers. <IMAGE>
