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.

A control circuit comprising:
- 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;
- 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.
(canceled)
A power system comprising:
- a low side power source coupled to a traction boost converter;
- a high side power source coupled to the traction boost converter;
- and
- a control circuit configured to control a power output of the low side power source based on a state of charge of the high side power source.

-49. (canceled)
A method of operating a control circuit comprising the steps of:
- operating a circuit to determine a state of charge of a high side power source and adapted to provide a variable gain signal based on the state of charge;
- operating a circuit to provide a fixed gain signal based on current from the high side power source;
- and
- operating a circuit to combine at least the variable gain signal and the fixed gain signal to create a power command.
