Greetings, I am working on a capacitor discharge circuit to charge a super capacitor bank. I am having limited success using PWM. I am searching for a SCR circuit to increase performance, suggestions welcome. When the input cap bank is charged to 150 volts dc it can supply a 10 pulse to the super cap bank. The reason for this project is to reduce operation fatigue created from the BEMF braking.
