Each phase of the multi-phase power system receives generated powers from a set of inverters, and each phase has a set of switch reactive elements for making power factor adjustments to the power generated by the set of inverters. The power outputs of the set of inverters belonging to a particular phase are combined into a one combined ac power output, and the power factor adjustment for that particular phase is performed on the combined power output by the set of the switch reactive elements of that particular phase. In some embodiments, at least some of the inverters are micro-inverters that convert DC power from one or two solar panels to AC power.

摘要： A DC to AC power converter is disclosed. The power converter has four power-switching devices, two diodes, a step-up and isolation transformer, a capacitor-choke filter and a controller. Two power-switching devices located on the primary side of the transformer are switched to provide alternate cycles of an ac current to the primary side of the transformer, which magnetically couples the ac current to the secondary side of the transformer. Two power-switching devices on the secondary side of the transformer are switched to alternately allow the forward and return ac currents from the secondary side of the transformer in the output path to a load connected to the output of the DC to AC power converter.

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.
