Abstract
A control circuit comprises a circuit adapted to determine a state of charge of a high side power source using a sensed output current to provide a variable gain signal based on the state of charge. The control circuit may also contain a circuit configured to provide a fixed gain signal based on the current of the high side power source and a circuit configured to combine the variable gain signal and the fixed gain signal to create a power command.
