Abstract: This invention proposes using a feed forward quasi universal converter for energy harvesters, and uses it to power IoTs (Internet of things). A typical DC to DC converter uses voltage feedback control or current feedback control. It is not easy for the input impedance to closely match the output impedance of the power source. In the meantime, it also meets its output voltage and power targets. The Feed forward Quasi Universal Converter proposed in this invention controls the input impedance and the output voltage/power within a range that meets the design targets. It is also achieved with a simple electronic adjustment when the source impedance changes or the output requirements change. It has the potential to shorten the IoTs system industry's product development cycle, reduce installation and maintenance costs and facilitate the adoption of hybrid energy sources.
