ABSTRACT:
A power unit includes a plurality of substantially identical battery units connected in series and/or in parallel by respective switches. Said switches are actuated by a central control unit in accordance with requirements of a load. A solid switch member provides linearization and PM modulation at the graded output voltage in order to attain a low-ripple output voltage. Said graded DC output voltage can be further converted into AC output.
