Equipment temperature regulating circuit

ActiveCN102830734AIncreased power supply rippleAvoid excessive heatTemperatue controlVoltageSetting time
The invention discloses an equipment temperature regulating circuit which comprises a temperature detecting circuit, an integrating negative feedback circuit and a first heating control circuit. The temperature detecting circuit is used for detecting temperature of equipment, converting the detected temperature into voltage and outputting the voltage to an input end of the integrating negative feedback circuit from a voltage output end of the temperature detecting circuit. Reference voltage is accessed to the other input end of the integrating negative feedback circuit. Voltages at two input ends of the integrating negative feedback circuit are compared to each other, high-level or low-level control voltage is output from an output end of the integrating negative feedback circuit according to the comparison result and used for controlling heating of the first heating control circuit. The time for changing low level to high level of the control voltage and the time for changing the high level to the low level of the control voltage are longer than set time. The heating temperature point can be regulated by regulating the reference voltage, so that heating temperature points of the equipment having different temperature requirements can be regulated conveniently. In addition, since the process of changing the level of the control voltage is gradient, mutated current is avoided, and power supply ripple cannot be increased.
