System and method for regulating a power system with feedback using current sensing

A method for regulating a power system, comprising:

• setting a correction signal to a first predetermined value corresponding to a desired output load voltage;
• determining a first actual output load voltage value;
• selectively adjusting the correction signal based on the first actual output load voltage value;
• and
• determining an offset voltage associated with a sense amplifier within a current controller in the power system using the adjusted correction signal.

A method for regulating a power system having a current controller coupled to a voltage controller, the method comprising:

• determining at least one of an offset voltage associated with a sense amplifier within the current controller and a closed loop gain error associated with the power system;
• determining an actual output voltage provided by the power system and a desired output voltage of the power system;
• and
• determining a correction signal based on the determined at least one of the offset voltage and the closed loop gain error, the actual output voltage, and the desired output voltage.

• determining a first actual output load voltage value with the voltage controller;
• selectively adjusting the correction signal based on the first actual output load voltage value to provide an adjusted correction signal;
• sensing with a sense amplifier a differential between the adjusted correction signal and a sensed line current of the power system to provide a control signal for controlling voltage across an output load;
• and
• determining a gain slope error using the voltage controller, the gain slope error corresponding to the power system using the adjusted correction signal.
