A.C. power supply having combined regulator and pulsing circuits

摘要

A circuit for producing an alternating output current may comprise a first current regulator and a second current regulator. The first current regulator produces a first phase of the alternating output current and regulates the current of the first phase. The second current regulator produces a second phase of the alternating output current and regulates the current of the second phase. A first polarity reversing circuit operatively associated with the first current regulator periodically reverses the polarity of the first phase. A second polarity reversing circuit operatively associated with the second current regulator periodically reverses the polarity of the second phase. A control system operatively associated with the first and second current regulators and the first and second polarity reversing circuits controls the operation of the first and second current regulators and the first and second polarity reversing circuits.
