I have designed a simple circuit that harvests energy that is generated from an electromagnetic generator.
I would like to know tips I could use to improve efficiency and minimize the losses I may have by using this design. I have drawn h the circuit for more clarity.
Please note the MOSFETs act like a diode bridge. This circuit has been tested and it works. I am interested in improving the efficiency including any other options that may even be costly.
The following are requested information as per comments.
The voltages peaks generated from the harvester has about 7v Pk-Pk. This depends on speed. I have mentioned the average.
The purpose of the zener is only to protect the BQ25505 from receiving beyond 5.5V. That is the maximum input voltage of the BQ IC.
High Spikes of 6V are reduced because of the capacitors charging effect. We have tested this and its true.
Currently i want to more efficiently harvest the energy bursts coming off the harvester. With lowest dropout voltage.
