Systems and methods for producing a substantially constant output voltage in a power source boost system

A power source boost system, comprising:

• a voltage source;
• a power supply boost circuit comprising:
• an output node for supplying an output voltage (Vout),
• a feed forward loop coupled to the voltage source, and
• a feedback loop coupled to the output node, the feedback loop comprising a voltage limiter coupled to the feed forward loop;
• and
• a load coupled the voltage source, the output node, and the feed forward loop.

A method for producing a substantially constant voltage at an output of a power source boost system coupled to a load, the power source boost system including a feedback loop comprising a limiter coupled to the output and a feed forward loop coupled the limiter, the load, and the power source, the method comprising the steps of:

• comparing, via the feedback loop, the constant voltage to a reference voltage;
• and
• stabilizing the power source boost system over a range of input voltages and load variations,
• wherein the stabilizing step comprises the step of limiting, via the limiter, a voltage supplied to the feed forward loop to a predetermined range of voltages based on the comparing step.
