To find the right configuration for the source, it is crucial to understand the voltage/power behaviour of the harvester under various environmental conditions. The most straightforward approach is to perform a voltage sweep across the harvester terminals in a controlled environment and measure the current provided by the harvester at different voltages. By multiplying the voltage by the current, the power generated at different source voltages can be calculated. This process should be repeated for different environmental conditions.
Once the harvester is characterized under various conditions, it’s possible to determine whether constant voltage regulation or regulation based on the open-circuit ratio is required.
