Abstract: A power inverter, such as a synchronous buck power inverter, that is configured with a high frequency switching control having a (PWM) controller and sensing circuit. Controller provides a low frequency oscillating wave to effect switching control on a synchronous-buck circuit portion that includes a plurality of switches to invert every half cycle of the frequency provided by controller. The inverting process thus creates a positive and negative transition of the oscillating wave signal. A low frequency switching stage includes a further plurality of switches configured to operate as zero voltage switching (ZVS) and zero current switching (ZCS) drives Charge on an output capacitor is discharged to zero on every zero crossing of low frequency switching stage and advantageously discharges energy every half cycle. During this discharge of energy, the zero crossing distortion in the low frequency sine wave is greatly reduced.

Abstract: Systems and methods are disclosed that operate to correct the electrical characteristics of an electric distribution system based on analysis at a particular point in the system, for example, at a customer's meter. To do so, the subject characteristic may be measured at the meter. The subject characteristic may be provided to a power inverter controller, which responds by modifying the characteristic of the inverter output to achieve the desired measurement at the meter.
