Current Waveform Construction to Generate AC Power

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.

Some apparatus and associated methods relate to conductivity modulation apparatus for active operations with an inductive element in a packaged circuit module formed with a bypass switch for configuration in parallel with an inductor. In
