Abstract: An AC power supply includes a digital feedback loop for output regulation. The feedback loop generates an RMS control signal that is mixed with a desired waveform to produce an input for a feedback loop that generates an instantaneous control signal. The instantaneous control signal is used to regulate power supply output.

Abstract: An electrical DC-to-AC power conversion apparatus is disclosed that is primarily intended for use with solar photovoltaic sources in electric utility grid-interactive applications. The invention improves the conversion efficiency and lowers the cost of DC-to-AC inverters. The enabling technology is a novel inverter circuit topology, where throughput power, from DC source to AC utility, is processed a maximum of 1½ times instead of 2 times as in prior-art inverters. The AC inverter output configuration can be either single-phase, split-phase or poly-phase.

Abstract: A computer readable, media and signals for controlling power drawn from an energy converter to supply a load, where the energy converter is operable to convert energy from a physical source into electrical energy. Power drawn from the energy converter is changed when a supply voltage of the energy converter meets a criterion. The criterion and the change in the amount of power drawn from the energy converter are dependent upon a present amount of power supplied to the load. The methods, apparatus, media and signals described herein may provide improvements to DC to AC maximum power point tracking in an energy conversion system such as a photovoltaic power generation system.

Abstract: The invention is a device and method for eliminating core excitation losses in a distribution transformer when the transformer is not supplying power to loads. The invention consists of sensors, a control circuit, a user interface and a power contactor. The power contactor is connected on the line side of a transformer and is opened or closed automatically based on preprogrammed time or load criteria determined by the control circuit. In one operational mode and when the transformer is disconnected from the line, the control board generates low power pulses at the transformer load connection points in order to “search” for loads. If a load is detected, the transformer is reconnected by way of contactor closure. If the transformer load drops to zero, for a predetermined amount of time, the transformer is again disconnected and the pulsed load search is reestablished.

Abstract: Methods, apparatus and media for controlling a switching circuit controlling an amount of power drawn from an energy converter, to optimize the amount of power drawn from the energy converter. An output voltage and an output current of the energy converter are measured to produce signals representing converter output voltage and current. Converter power is calculated from the product of the converter output voltage and current. A perturb voltage is calculated as a decreasing nonlinear function of the converter power. A new reference voltage signal representing a desired converter output voltage is produced in response to a previous reference voltage signal and the perturb voltage. The reference voltage signal is used by the switching circuit to adjust the power drawn from the converter to achieve the desired converter output voltage.
