Abstract

A circuit connects a low-voltage high-current DC power source (P L) in series with a high-voltage low-current DC source (P D). The series connection is made under full power by using the second source P L to commutate the load current and allow the first source P D to be reconfigured from series to parallel operation, doubling its current rating.
