    Abstract: The present disclosure provides an energy conversion system and method for generating electricity directly from heat by phase transformation of ferroelectric materials without any external power sources. The energy conversion system includes an electric circuit comprising a phase-changing capacitor and a charge reservoir. The phase-changing capacitor has a dielectric layer comprising a phase-transforming ferroelectric material. When the phase-changing capacitor is initialized and subjected to thermal cycles through a transformation temperature of the phase-transforming ferroelectric material, the polarization of the dielectric layer undergoes an abrupt change between a ferroelectric phase and a paraelectric phase such that a current flow between the phase-changing capacitor and the charge reservoir via a load thereby converting heat into electrical energy. The present energy conversion method does not require any external bias fields during the energy conversion.

  • Patent number: 10637279
    Abstract: Effects of a surge in an AC input voltage to a UPS is mitigated. If the AC input voltage is overvoltage, the rectifier is operated using a DC bus target voltage for the DC bus voltage unless the rectifier reaches its current limit. If the rectifier reaches its current limit, the DC bus target voltage is increased by a predetermined amount which is used as a current DC bus target voltage unless the increased DC bus target voltage exceeds a maximum DC bus voltage limit in which case the current DC bus target voltage is set to the maximum DC bus voltage limit. The rectifier is then operated using the current DC bus target voltage until it reaches its current limit or the AC input voltage surge has passed. If the rectifier again reaches its current limit, the above steps starting with increasing the DC bus target voltage are repeated.
