Abstract
An optimizer circuit is interposed between a DC bus and a battery of a power supply system, including two converters in parallel, one that can lower the battery voltage below the bus voltage or directly connect the bus to the battery and one that can raise the voltage to the battery above the bus voltage. A controller actuates the two converters for optimizing battery charging and maintenance and for providing the battery power to the bus if other sources supplying the bus are not available.
