Abstract
A method for operating an electrocaloric system includes determining an internal temperature lift of an electrocaloric device. A current temperature of a space to be cooled is determined. A heat rejection temperature is determined. A difference between the current temperature and the heat rejection temperature is determined. A target temperature lift is determined based on the difference and a target temperature for the space. A voltage applied to the electrocaloric device is modulated based on the internal temperature lift and the target temperature lift.
