Figure 2: General block diagram of a voltage source inverter. We may infer from Figure 2 that the DC link capacitor''s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to

However, nominal power of the capacitor is reached at its rated voltage, so i.e. 20kvar at 440V. If the mains voltage is 400V, capacitor nominal voltage 440, and reactor cause voltage change at the capacitor terminals as well as launch additional reactive power to the circuit, all the calculations introduced in this article must be done.
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.
