Ultracapacitor With Converter

This example shows how a DC-DC converter can be used to maintain a constant load voltage when drawing power from an ultracapacitor. Initially the converter supplies power to the load, and as it does so, the capacitor voltage drops. The protection circuit disconnects the load when the capacitor voltage drops below a threshold of 4V. At 10 seconds the generator is turned on, and power is supplied to both the load and to the capacitor to recharge it.
