NOVELTY - The method involves constructing a current waveform that contains a sequence of current signals of alternating polarity. The constructed waveform contains a period corresponding to a fundamental frequency. Each current signal is formed within one-half of one period by turning on a switch (232) corresponding to the polarity of the current signal that is constructed. The current is decreased to substantially zero by directing the current that continues to flow after the switch turns off to recharge a capacitance.    USE - Method for shaping a current waveform for supply to a transformer primary winding to convert alternate current power for distribution by using power conversion system to a high voltage electrical distribution network from renewable energy sources e.g. wind, wave, solar, geothermal, and/or hydrokinetic energy sources.    ADVANTAGE - The method converts energy from natural or renewable sources to electrical form, and constructs the current waveform on a primary winding of a transformer by recapturing inductive energy previously stored in the transformer to transform the converted electrical energy to sinusoidal alternate current (AC) voltage at a secondary winding of the transformer, thus providing low harmonic distortion AC power for distribution to a high voltage electrical distribution network, and hence reducing switching losses and reducing or eliminating generation of conducted or radiated electromagnetic interference from an inverter to eliminate requirement of high frequency filtering of power conversion circuits to reduce cost, size, weight, and component count, while improving manufacturability, minimizing a number of transformer stages to reduce parts count, avoid substantial efficiency penalties, and variable output voltage that is regulated by simple selection of pulse width to produce a desired AC output voltage on the secondary side of the transformer, and reducing a cost of a cabling without incurring substantial voltage drop and/or power dissipation due to resistance in conductors.
