  • Patent number: 10411474
    Abstract: An electric power system includes a variable-frequency drive and a control module. The variable-frequency drive includes a first power converter, a second power converter and at least one energy storage module. The first power converter is connected between a DC bus and a power terminal. Moreover, electric energy is transferred between the first power converter and the power terminal at a first power. The second power converter is connected between the DC bus and an electric/kinetic energy conversion device. Moreover, electric energy is transferred between the second power converter and the electric/kinetic energy conversion device at a second power. As the second power is dynamically changed, the control module controls a charge/discharge operation of the at least one energy storage module. As a consequence, the operational change of the electric/kinetic energy conversion device is reversely compensated.

  • Patent number: 10298057
    Abstract: A double-sided LCLC-compensated network is proposed for a capacitive power transfer (CPT) system. In one design, four metal plates are used to form two power transmitting and receiving capacitors and the LCLC network is used to compensate the capacitors. In the second design, two extra metal plates are used to couple with the previous four plates at the transmitting and receiving side, respectively, which forms the capacitor-integrated structure. The circuit parameter values are tuned to achieve zero voltage switching (ZVS) of the input side switches. There is also a CLLC topology proposed, which is a similar variation of LCLC circuit. A 3.3 kW input power capacitive power transfer prototype is designed and built. The experiment results show that the proposed CPT system can transfer 3.1 kW output power through an air gap distance of 70 mm with a dc-to-dc efficiency of 92.1%.

The process includes providing a first solution of a polymerizable material in a solvent, and providing a first environment proximate a first region of the coating and a different second environment proximate an adjacent region of the coating. The process further includes at least partially polymerizing the polymerizable material to form a composition that includes an insoluble polymer matrix and a second solution. The insoluble polymer matrix includes a plurality of nanovoids that are filled with the second solution, and a major portion of the solvent from the second solution is removed. A first volume fraction of the plurality of nanovoids proximate the first region of the coating is less than a second volume fraction of the plurality of nanovoids proximate an adjacent of the coating.
