摘要： This power converter is provided with: three clusters (CLu, CLv, CLw) in which unit cells are cascade-connected; and power supplies of the same kind which are respectively connected to one end of each of the three clusters. Terminals of the three clusters at the side not connected to the power supplies are respectively connected to other ends of the power supplies connected to the other clusters to form a delta-connection configuration. Three connections of the delta-connection configuration are respectively connected to each of the U, V, and W phases of a three-phase alternating current, and power conversion between the power supplies and the three-phase AC is enabled. If DC power supplies (Vdcu, Vdcv, Vdcw) are employed as the power supplies, power conversion between the DC power supplies and the three-phase AC power supplies can be performed. If in-phase single-phase AC power supplies are employed as the power supplies, power conversion between either the single-phase AC power supplies and the three-phase AC power supplies, or the three-phase AC power supplies can be performed.

摘要： A power transfer system includes a power transmission device and a power reception device which are capacitively coupled to allow electrical conduction therethrough in the manner of alternating current. The power transmission device includes an active electrode, a passive electrode, a step-up transformer, and a high-frequency voltage generating circuit. The power reception device includes an active electrode, a passive electrode, and a load circuit. A divider for voltage division based on load capacitances (C1 and C2) is provided between the active electrode and the passive electrode. The active electrode and the passive electrode have respective equivalent capacitances to ground (Ca and Cp) relative to the ground potential. A ground leakage current Ig is minimized by adjusting the values of the respective capacitances in an equivalent circuit so as to satisfy the relationship: C2/C1=Cp/Ca.

摘要： Methods and systems for transforming electric power between two or more portals. Any or all portals can be DC, single phase AC, or multi-phase AC. Conversion is accomplished by a plurality of bi-directional conducting and blocking semiconductor switches which alternately connect an inductor and parallel capacitor between said portals, such that energy is transferred into the inductor from one or more input portals and/or phases, then the energy is transferred out of the inductor to one or more output portals and/or phases, with said parallel capacitor facilitating “soft” turn-off, and with any excess inductor energy being returned back to the input. Soft turn-on and reverse recovery is also facilitated. Said hi-directional switches allow for two power transfers per inductor/capacitor cycle, thereby maximizing inductor/capacitor utilization as well as providing for optimum converter operation with high input/output voltage ratios. Control means coordinate the switches to accomplish the desired power transfers.
