Abstract
The outputs of a plurality of modules or generators of electrical energy, such as fuel cells, chemical storage batteries, solar cells, MHD generators and the like, whose outputs are different are consolidated efficiently. The modules supply a power distribution system through an inverter. The efficiency is achieved by interconnecting the modules with an alternating voltage supply and electronic valves so controlled that the alternating-voltage supply absorbs power from modules whose output voltage is greater than the voltage at which the inverter operates and supplies this power as a booster to modules whose output voltage is less than the voltage at which the inverter operates.
