hi,
i am trying to do a regenerative braking model. I am using a 12v permanent magnet dc motor. I ve coupled a freewheel to the motor shaft so that on braking(cutting of supply from motor by using a DPDT switch) the voltage generated by the motor gets collected onto the capacitor connected to the other terminal of the DPDT switch. It is working and showing constant rise in the capacitor charge. the capacitor charge stays for a very long time successfully since i have put a diode and a resistor in series with the motor terminal and the capacitor. I am now trying to use the charge of the capacitor to light up an led which i am not able to light since the voltage stored in the cpaciotr is very small about 1.5 volts and the led lights up on 2.5 volts. can anyone please suggest me a method in which i can amplify this capacitor voltage so as to light the led. presently i am thinking of using a dc-dc step up converter,but yet to test it.please help.
