Learn MoreIn this article we will discuss about the sources of over-voltage and its protection. Sources of Over-Voltage: Transients are disturbances that occur for a very short duration (less than a cycle) and the electrical circuit is quickly restored to original operation provided no damage has occurred due to the transient. An electrical transient is a cause-and-effect …

Learn MoreEngineers who deal with power supplies (as most eventually do) often see the circuit-protection terms "crowbar" and "clamp." No, there are no references to items purchased at the local hardware store, but they are essential "hardware" elements, meaning autonomous circuit components and functions with no related software.
Learn MoreThis means I can not guarantee the voltage feeding the supercap is within the capacitor''s limits, so I have to make a circuit which protects the supercap against dangerously high voltages. I''m planning on …
Learn MoreFor even more protection, would a 2.7V zener-diode with a resistor in series be sufficient? This combination would be soldered across each capacitor. I have a superstrong/fast microcontroller with enough outputs I could use, I just don''t know what components/ICs I have to use. Edit 1: Thanks for all the feedback, I will go with this circuit

Learn MoreYes you can easily end up stressing a capacitor due to overvoltage. If you are going to charge the capacitor string at say 10A (your PS in CC mode), then you must allow for the possibility that any one of the caps may enter overvoltage (whatever you select as the terminal voltage . this case 2.7V maximum).
