I need advice if it is possible to replace switches ( see drawings ) with suitable transistors and other parts.
- Base leg voltage to "open" transistor ~0.2 - 0.3 Volts.
- Transistor remains "open" until base leg voltage drops to less then 0.1 Volt. OR duration for "open" position of transistors 5-10 seconds to allow maximum energy transfer from C1 and C2 to C3.
- Amperage levels on all stages are 0-2 Ampers.
Purpose of this device is to "upgrade" energy available from very low-level sources to more useful levels. I tried many different kinds of DC to DC up-converters. Some of them are really well made and do great job.
But all of them have very low efficiency levels (10 - 40 % ) and if more higher level of upgrade requested ( for example from 0.1 Volt to 5 volts ) lower is efficiency. Multitude of experiments show that supercapacitors ( directly connected to the source ) do much better job. Circuit on the drawing works, but need constant human intervention. I think automation of this process is possible.
My knowledge and practical experience in Electronics are very poor. Please, help with selection of components needed for this unit from existing marketplace.
