摘要： A multi-stage electric voltage converter is disclosed. The converter comprises a voltage source and multiple stages. Each stage of the multiple stages comprises a first and a second and a third switch, and a capacitor, wherein the capacitor is coupled to the voltage source by the first and the second switches and each stage is coupled to a different stage or to an output of the multi-stage electric voltage converter by the third switch so as to allow the capacitor to be charged by the voltage source when the first and the second switches are closed and the third switch is open, and to allow the capacitor to be connected to the output of the multi-stage electric voltage converter when the first and the second switches are open and the third switch is closed.

摘要： A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs. A first bidirectional power converter is employed in a sealed battery unit having no external electrical contacts. A second bidirectional power converter is employed in a corresponding cart bidirectional power converter assembly. The battery unit and the cart bidirectional power converter assembly cooperate to wirelessly transmit power from the battery unit to a load of the cart bidirectional power converter assembly and from a power source to the battery unit via the cart bidirectional power converter assembly.

摘要： In a 12-pulse AC/DC converter of the hexagon type the rectifier switches are distributed in three groups for each polarity and for each polarity three coils are joined to the common pole and connected separately to the pairs of rectifier switches of a corresponding group. As a result, the capability of the hexagon is extended to commutation of diodes, instead of controlled rectifier switches, by the effect of such interposed commutation inductance.

摘要： A management or control of a power router is more appropriately performed when a power network system in which power cells are asynchronously connected with each other. A plurality of power conversion legs bi-directionally convert power, one ends thereof are connected with a direct current bus and the other ends thereof are connected with an external connection partner as an external connection terminal. A control unit controls operations of the plurality of power conversion legs. The control unit receives a control instruction including a designation of a stopping target leg. The control unit performs an adequacy determination of whether the stopping target leg can be stopped. The control unit stops the stopping target leg when the stopping target leg can be stopped.

摘要： A unity power factor converter capable of effecting either inversion (dc-to-dc) or rectification (ac-to-dc), and capable of providing bilateral power control from a DC source (or load) through an AC transmission line to a DC load (or source) for power flow in either direction, is comprised of comparators for comparing the AC current i with an AC signal i.sub.ref (or its phase inversion) derived from the AC ports to generate control signals to operate a switch control circuit for high speed switching to shape the AC current waveform to a sine waveform, and synchronize it in phase and frequency with the AC voltage at the AC ports, by selectively switching the connections to a series inductor as required to increase or decrease the current i.

摘要： A fault switch configuration and clearing method in a flexible DC converter station, the flexible DC converter station is configured with a grid side switch and a valve side phase-split switch in the converter station. When a fault occurs, a faulty phase and a non-faulty phase are detected and identified by means of differential protection or low voltage overcurrent. An alternating current zero crossing condition is created by means of firstly turn off the non-faulty phase valve side phase-split switch and the grid side switch, thereby cutting off the faulty phase, disconnecting the connection between a power supply and a fault point, and achieving the clearing for faults. The described fault-clearing method is simple and practical, highly reliable, and connection between the fault point and the power supply is quickly and effectively cut; converter station equipment is effectively protected, and further expansion of the fault is avoided.
