Abstract: A system for supplementing the electric power needed by a pump jack electric motor, thereby reducing the electric power purchased from the local utility or power supplier. The system comprises a solar photovoltaic system, or other forms of renewable energy, and regenerated power from the electric motor or drive. The system can be both “on-grid” and “off-grid.” Battery banks and capacitor banks may be used to store and provide energy.

Abstract: The invention relates to a grid synchroniser for connecting an AC output of a power converter to the AC grid mains. In one aspect the invention provides a grid synchroniser comprising an inverter controller to control an AC output of the inverter, the controller including a receiver to receive grid data from a grid sensor location remote from said inverter. In another aspect we describe techniques for rapid removal of charge from a control terminal of a power switching device such as a MOSFET, IGBT or Thyristor using a particular driver circuit.

Abstract: A method of starting a power system including an inverter having a plurality of DC feeds, wherein the DC feeds include a first DC feed and a number of additional DC feeds. The method includes connecting the first DC feed to a DC link of the inverter, synchronizing the inverter to an AC grid, and connecting the synchronized inverter to the AC grid. The method also includes, for each of the additional DC feeds, responsive to determining: (i) that a predetermined time period based on a required power ramp rate of the inverter has elapsed, and (ii) that current operating conditions of the inverter are within a safe operating area of a plurality of switching devices of the inverter, connecting the additional DC feed to the DC link.

Abstract: A multi-function power converting apparatus including an inverter circuit and a controller is provided. The inverter circuit drives a load. The controller generates a control signal according to a sampled DC voltage, a sampled AC voltage, a load current, and an output current. The controller causes the inverter circuit to enter an uninterruptible power supply mode or a grid-connected power supply mode through the control signal. Specifically, when the inverter circuit enters the grid-connected power supply mode, the multi-function power converting apparatus operates in one of a mixed real-virtual power output mode, a rectification charging mode, an active filtering mode, and an active power balancing mode.
