摘要： Apparatus and associated methods involve a controllable supply adapted for controlling switch phasing and pulse width to substantially equalize power in adjacent quadrants of a sinusoidal source voltage waveform to regulate reactive power drawn from the source. In an illustrative example, the supply may, in some embodiments, deliver power to a load at a level responsive to a commanded input signal. In some examples, the power supplied to the load may be adjusted according to the command input signal to a selected value within an operating range. In some examples, the operating range may include a portion or all of 0 to 100% of rated load. Various embodiments may be adapted to supply unipolar or bipolar load excitation. In some embodiments, high power factor may be maintained over a substantial range of commanded power to the load. Certain embodiments may enhance supply efficiency by capturing and recycling inductive load energy.

摘要： Apparatus and associated systems and methods may relate to a process for supplying unidirectional current to a load, controlling a reverse electromotive force (REMF), capturing inductive energy from the load, and supplying the captured inductive energy to the load. In an illustrative example, an operating cycle may include a sequence of operations. First, inductive energy captured from the load on a previous cycle may be supplied to the load. Second, energy may be supplied to the load from an external power source. Third, a REMF voltage may be substantially controlled upon disconnecting the power source from the load. Fourth, the load current may be brought to zero by capturing the inductive energy for use on a subsequent cycle. In some embodiments, a single power stage may supply a DC inductive load, or a pair of power stages may be operated to supply bidirectional current to an AC load.

摘要： Methods and apparatus to provide low harmonic distortion AC power for distribution by converting energy from natural or renewable sources into electrical form, and constructing a current waveform on a primary winding of a transformer by recapturing inductive energy previously stored in the transformer so as to transform the converted electrical energy into substantially sinusoidal AC voltage at a secondary winding of the transformer. For example, AC power may be supplied to a utility power grid from raw electrical energy from renewable energy sources (e.g., solar cells). An inverter may construct the primary winding current waveform using two unidirectional switches. On each half cycle, one of the switches first applies energy previously recaptured from primary winding inductance, and then applies the raw energy to the transformer primary winding at the utility power grid frequency. Accordingly, the constructed primary winding current may exhibit substantially improved total harmonic distortion.
