I Try to use a joule thief circuit to harvest energy from almost die battery. But the reference that i found on forum or conference paper just explain how joule thief circuit works, not the configuration and mathematical modelling for achieving best energy harvesting configuration.

Anybody can explain or give me a reference about mathematical modelling of joule thief circuit?

Thank you,

    \$\begingroup\$ The circuit you used earlier has problems, with respect to your solar cell specifications. You also haven't discussed how you made your measurements regarding the solar cell, as well. The Joule Thief circuit has some varieties, as well. There isn't a "single circuit" to discuss. Instead, it's more like a meandering dialog discussing the problems with the simpler iterations and walking through various iterative ideas about improving it. But it is mainly used for extracting the last bit of energy from a battery and a lot less about solar cell usage. So this is a wide-ranging discussion, really. \$\endgroup\$ – jonk May 24 at 5:34

    \$\begingroup\$ That circuit needs a higher voltage to generate 50% efficiency like 2 or 3 V Would you like me to show you? \$\endgroup\$ – Sunnyskyguy EE75 May 24 at 6:42
