High temperature protection system for adjusting duty cycle by using pulse width modulation signal
High temperature protection system includes a thermal detection and control circuit, a pulse width modulation signal output circuit, a driving circuit, and a coil module. The thermal detection and control circuit is used for detecting a temperature and outputting at least one corresponding control signal. The pulse width modulation signal output circuit is coupled to the thermal detection and control circuit for generating a pulse width modulation signal according to the at least one control signal. The driving circuit is coupled to the pulse width modulation signal for generating at least one driving voltage. The coil module is coupled to the driving circuit and is operated according to the at least one driving voltage.
