Circuit Models of Pyroelectric Charger
Abstract
In the framework of electrical engineering notions, we suggest a model of a pyroelectric charger. The pyroelectric charger (also called pyroelectric sandwich) includes both metal conductors and a dielectric pyroelectric crystal. Depending on the scope of applications, the charger can be modeled on different levels of complexity, ranging from basic schematic models, adopted in electrical engineering, to extremely sophisticated models, incorporating contemporary condensed matter physics. In this report, we focus on the models adopted in electrical engineering. These models are based mostly on circuit theory and ordinary differential equations. We analyze two extreme regimes: the quasi-static regime, in which the polarization does not change, and the explosive regime, in which the polarization abruptly changes or completely disappears. More elaborate models, based on using partial differential equations, will be analyzed in future reports.
