摘要： A controlled electrical energy storage apparatus for selectively storing electrical energy from an electrical grid, and selectively releasing the electric energy back into the grid. The apparatus includes a converter coupled to the grid, and a DC energy storage device coupled to the converter. The converter includes a switching circuit having a plurality of high speed electrical switches arranged in pairs. Each switch pair is coupled between one of the phase lines of the AC utility grid and the DC energy storage device. The power flow control unit supplies a power flow control waveform to the switch pairs. The power flow control waveform includes a real waveform for control of real power and an imaginary waveform for control of reactive power independently of the real power. By pulse-width modulating the switches at a high frequency, the converter controls instantaneous currents flowing through each of the phase lines for precise control of the real and reactive power.

摘要： A low impedance, low noise laminated bus assembly for a high power switched converter that has a plurality of switch pairs including a -DC switch and a +DC switch for high speed switching to convert between an AC power line and a DC power storage device such as capacitors. The laminated bus assembly includes a first conductor plane having a plurality of AC bar conductors for each phase of AC power, a second conductor plane including a -DC bar conductor, and a third conductor plane including a +DC bar conductor. A dielectric layer is laminated between the first, second, and third planes. The circuit layout includes a plurality of electrical connections between the switches, the AC, -DC and +DC bar conductors, and the DC power storage device. Some of the electrical connections require that a coupling conductor pass through another bar conductor, which must therefore be insulated from the coupling conductor. Each bar conductor therefore has at least one insulated hole that includes an annular insulator through which the coupling conductor, which is a bushing, is inserted.

摘要： A low impedance, high power bus for conduction of electrical power with reduced transient signal effects is described herein. The high power bus can be applied as a high power supply bus between a constant voltage source and a plurality of switching cells positioning at varying locations along the bus, and as branch bus for the switching cells. The power bus can transmit high power: large currents in the hundreds or thousands of amperes, and large voltage potentials in the hundreds or thousands of volts. Particularly, the power bus has use in a DC-to-AC inverter that converts DC from a constant voltage source into three-phase AC for delivery to an electrical power grid. The high power bus includes two conductive bars positioned so that the current flow therethrough is balanced (equal and opposing), and the magnetic field is substantially confined between the bars. The bus includes a dielectric positioned between the conductive bars. In a preferred embodiment, the AC is conducted on extension bars that extend along the power supply bus, so that a main bus is created by the combination of the AC extension bars and the DC power supply bus, and the sum of the currents in the bars is approximately zero at all locations in the bus. The power bus lessens or even obviates the need for the snubber networks commonly used to reduce transients, and reduces the strength of magnetic fields and electric fields that could otherwise interfere with neighboring electrical components.

摘要： An inverter control is used to control the output of a distributed power generating station, such as a photovoltaic (PV) solar power station, connected to a power grid. The power station is connected to an inverter output. Pulse width modulation is used to shape the output in order to maximize power output within power quality parameters and provides control of a switching frequency of the inverter responsive to a sensed parameter. The technique allows an increase in output efficiency and provides for adjustment of power output to meet power quality parameters to an extent required in order to connect to the power grid.

摘要： A group of solar power stations with inverters are adjusted in order to achieve optimum power output in accordance with maximum power-point tracking (MPPT). The MPPT data is used to perform adjustments. Power measurement factors, including Maximum Power Points (MPPs) are established to represent a bus-voltage setting that produces the maximum power output from an individual photovoltaic panel. These settings are established for the group so as to optimize power output under a variety of operating conditions.
