ABSTRACT:
A system for supplying d.c. power to an electrical load, in which such load includes a rechargeable battery, is characterized by a plurality of power sources connected in common to the electrical load, wherein the current generated by the multiple power sources is combined to supply such electrical load. Each of the power sources includes a solar panel and a controlled variable transconductance device, such as a Buck converter, connected in electrical series circuit. A digital processor, including a stored program, coupled to the control inputs of the variable transconductance devices, selectively individually sets the duty cycle of each transconductance device under control of a stored program, whereby the electrical power supplied by said power sources to said electrical load is individually controlled by the digital processor.
