PI Temperature Control Amplifier for Thermoelectric Cooler (TEC) Driver
https://www.electronics-lab.com/project/pi-temperature-control-amplifier-for-thermoelectric-cooler-tec-driver/
This is a simple Proportional, Integral (PI) temperature control amplifier. A complete thermoelectric cooler (TEC) controller can be created using this PI amplifier and OPA569 Power Op-Amp or other output amplifiers such as DRV591, DRV592 and DRV593. Proportional-integrator compensation is simpler to adjust and often provides an adequate thermal transient response to the TEC driver […]
PWM Temperature Controlled FAN using TC648 and NTC sensor
https://www.electronics-lab.com/project/pwm-temperature-controlled-fan-using-tc648-and-ntc-sensor/
The project described here is a switch mode fan speed controller for use with brushed or brushless DC motors. Temperature proportional speed control is accomplished using pulse width modulation (PWM). 10K Ohms NTC is used to sense the temperature. The project is built using TC648 chip and configured with auto-shutdown mode. In Auto-Shutdown mode, fan […]
