PWM controller for thermoelectric devices used in a climatization system
2021
South Florida Journal of Development
The present work describes the development of an open loop temperature control system in a container through a Peltier Cell. The control consists of applying a PWM signal to the thermoelectric device, which controls the temperature in a range of 5 to 90 °C. A study was carried out to characterize the frequency and duty cycle of the PWM and thus determine the best operating conditions for the thermoelectric element. In addition, a power stage was implemented to change the supply polarity in the
