As a result, this capacitor is similar to a steady bridge between the input (beginning) and output (end) of power electronic converters. In electric vehicles, the DC link capacitor protects the inverter circuit by absorbing sudden voltage increases. The DC link capacitor is made to be strong and capable of holding a signification amount of energy.
filter capacitor in this role. The current pulses charging the capacitor when the diode(s) are forward-biased are generally much briefer than the time the capacitor is discharging into the load. Due to the principle of Charge Conservation in a capacitor, these pulses are therefore quite a bit higher in amplitude than the load current.
The ceramic capacitor voltage dependence is striking. It is normal for X7R capacitor to have no more then 30% of rated capacity at rated voltage. For example - 10uF Murata capacitor GRM21BR61C106KE15 (0805 package, X5R) rated for 16V will give you only 2.3uF capacity with 12V DC applied at 25C temperature. Y5V is much worse in this respect.
Choose a capacitor with a voltage rating that is higher than the highest voltage your circuit would ever see.
