How thermistor works

NettetThe heat-generating device starts producing 2 watts at time zero, and then at 40 seconds this increases to 20 watts. The thermistor therefore heats up, and its resistance decreases thereby increasing the voltage across the PWM reference pins. This increases the PWM frequency which in turn increases average motor current, and the fan speeds … Nettet24. apr. 2024 · Two Types of PTC Thermistors.

If R1 is the NTC and R2 is an ordinary resistor, Vout increases when the temperature increases. If R2 is the NTC and R1 is an ordinary resistor, Vout decreases when the temperature increases. Generally Vout = Vin*R2/ (R1+R2) if we think the output current =0. If there's some substantial load, the formula is more complex. state of eligibility proof josaa https://boldinsulation.com
