Abstract: An electrical network including a power source, a flyback converter, a microcontroller, a PID controller, a voltage boost converter, a pulse width modulator integrated circuit, and a battery. The power source produces a charge with a voltage ranging from about 0.1V to about 0.8V and a power ranging from about 0.3 mW to about 100 mW. The flyback converter functions in discontinuous current mode. The microcontroller monitors the power source voltage, calculates a voltage response, and outputs a control signal for the voltage. The PID controller is a digital PID controller, an analog PID controller, or a combination thereof. The voltage boost converter utilizes the power source voltage and power to provide higher voltage power to the electrical network. The pulse width modulator integrated circuit sets a duty cycle and frequency for the flyback converter. The battery stores excess charge produced by the power source.
