As it happens on SMs of IGBT, open-circuit faults can be divided into two type: S1 open-circuit faults and S2 open-circuit faults. Table 1 summarizes the submodule capacitor fault characteristics of SM under different operating conditions. Because the analysis of all SMs is the same, we omit the subscripts in Table 1.

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

How to Select Capacitors

This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It depends to your budget because the higher the voltage, the expensive the capacitor is. It will also depend on the
