Plurality of programmable regulated power supplies share the load in a predetermined ratio with overall stability determined by the master supply

摘要: A plurality of programmable power supplies are connected in cascade and interconnected such manner as to provide that they share the load predetermined ratios so overall stability is determined substantially solely by characteristics master supply. Prior art combinations have been two general kinds. The first kind has called ''''piggy-back'''' where an unregulated supply series with a regulated An feedback circuit used control voltage across load. Such arrangement, however, cannot output less than ratio sharing be provided. second uses master-slave combination. slave There no hence, accuracy system governed stable accurate supplies. Offset drift, for example, may degraded
