Hi,
I am quite new to field of electronic circuits.
I have thermomagnetic prototype working on Faraday's law which gives an instantaneous output voltage of ~200mV (positive and negative next to one another, just like AC - ref pic attached) . and the frequency of this is about 1 signal per 2 minute.
I would like to know a method/ circuit which could store all these voltages (Let's say after about 10 min - it can store about 1V) and then I could light up an LED.
I tried connecting to a capacitor - But because this is a closed circuit (copper coils), the capacitor gets discharged back through it. and if i want to rectify the signal, I am not able to find any diodes which work below 200mV.
I tried LTC3108 circuit (Startup voltage of 50mV), but when i connect it , there is a voltage drop at the input - although the generator is generating 200mV, the voltage going into input of LTC3108 is just ~20mV. so it does not give any output.
Can anybody help me by suggesting a suitable method to light up an LED? (In simple words - because I am new to circuits ) I have attached V vs T from my generator for your reference.
