International ClassH02J 001/00AbstractA 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.Field of SearchPLURAL SUPPLY CIRCUITS OR SOURCESSerially connected sources Serially connected sources Serially connected sources Series-connected sources Selective or optional sources Predetermined sequence Connecting or disconnecting Digitally controlled Having plural converters for single conversion Plural inverters | |
