Device for voltage regulation of a solar generator

摘要

A device for the voltage regulation of a solar-type generator by the additive or subtractive connection of generator units to a common bus bar. A logic circuit controls the number of unregulated generator units being connected to the bus bar at any one time depending on the load. A single generator is permanently coupled to the bus bar which generator is regulated to provide improved overall regulation. This single, permanently connected generator is regulated by a series regulator having high feedback loop gain for substantially reducing the output impedance of the single regulated generator in comparison to the unregulated generators. An embodiment incorporating d.c.-a.c. choppers for supplying an a.c. load is also disclosed. In this embodiment, the choppers are directly controlled to effect coupling between a generator and the common bus bar.
