GSR Posted February 18, 2010 Report Share Posted February 18, 2010 Dear all, I tried to build up a circuit which controls current though a DC motor. The motor needs to generate strong torque; and the input power will be battery ~12V 2400mAh battery pack. Previously, the motor has been tested. The peak current needed is 5A@30V for ~1s. Then there will be 1 second break before another peak. My plan is to build up a "capacitor train" which has ~5 "high energy density" capacitors. My circuit will include a boost up circuit to change the 12V to 30V DC and then charge the capacitors. After that, the circuit will control the capacitors discharge the energy to motor in sequence; and it will control the recharge of capacitors. (The circuit has to be as small as possible) my questions is where I can find the small and "high energy density" capacitors for this circuit? Quote Link to comment
