摘要： An apparatus includes a mechanical switch and a solid-state switch, such as a diamond switch or antiparallel-connected thyristor pair, coupled in series between an AC source and the load, such as a substation input transformer. The control circuit may be configured to connect the AC power source to the load by closing the mechanical switch and turning on the solid-state switch thereafter. The control circuit may be configured to interrupt a connection of the AC source to the load by turning off the solid-state switch and closing the mechanical switch thereafter. Operations of the switches may be coordinated with a fuse coupled in series with the solid-state switch to address different types of fault conditions.

摘要： A power generation system in an embodiment includes a power generator, a rectifying and smoothing circuit, a converter, a voltage measurement unit, and a switch. The power generator outputs AC power. The rectifying and smoothing circuit converts the AC power to DC power and smooths the DC power. The voltage measurement unit measures an average voltage of the AC power or a voltage of the smoothed DC power. The converter transforms the smoothed DC power. The switch is disposed between the rectifying and smoothing circuit and the converter, and becomes an ON state when the measured voltage becomes a reference voltage or higher.

摘要： We describe a power conditioning unit with maximum power point tracking (MPPT) for a dc power source, in particular a photovoltaic panel. A power injection control block has a sense input coupled to an energy storage capacitor on a dc link and controls a dc-to-ac converter to control the injected mains power. The power injection control block tracks the maximum power point by measuring a signal on the dc link which depends on the power drawn from the dc power source, and thus there is no need to measure the dc voltage and current from the dc source. In embodiments the signal is a ripple voltage level and the power injection control block controls an amplitude of an ac current output such that an amount of power transferred to the grid mains is dependent on an amplitude of a sinusoidal voltage component on the energy storage capacitor.
