Power-supply apparatus
First Claim
1. Apparatus used in supplying power to a load, the said apparatus including a generator of electrical energy, the output voltage of said generator being variable over a limited range, a storage battery connected to said generator and to said load used in storing energy from said generator when the output of said generator exceeds the demand of said load and used in supplying energy to said load when the output of said generator is insufficient to supply the demand of said load, a differential-rated converter interfaced between said generator and said storage battery, said differential-rated converter having a power supply having a voltage approximately equal to the magnitude of said limited range, said differential-rated converter including:
- (a) auxiliary means used in supplying alternating current for said converter, said auxiliary means having an intermediate terminal and opposite end terminals, and having an output voltage between said end terminals approximately equal to said limited range,(b) inductive-reactance means connecting said storage battery between an output conductor of said generator and said intermediate terminal, and(c) a pair each of separately controllable asymmetrically conductive valves interposed in inverse parallel between each of said end terminals and the opposite output conductor of said generator, andsaid apparatus also including means, connected to said converter, used in controlling said converter to set said converter to conduct the flow of power into or out of said battery.

Abstract
Power supply apparatus including a generator of electrical energy, such as fuel cells, solar cells, MHD generators or the like, in which a storage battery is connected to the generator and to the load for supplementing the generator when the load exceeds its output or for storing energy from the generator when the generator output exceeds the load. A differentially rated, current-sourced, dual converter is interfaced between the storage battery and the generator for controlling the flow of power into or out of the battery.
