Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.

VS MKP capacitors feature a self-healing dielectric. In the event of a dielectric break- down in the coil (short circuit), the metal coating vaporises around the breakdown site owing to the high temperature of the transient arc that is produced.
VS capacitors are designed for continuous operation at the specified nominal voltage and temperature, whereby IEC 61048 A2 provides for a permissible failure rate of 3% over the capacitor's service lifetime of 30,000 hours. Exceeding either the nominal voltage or temperature will shorten the capacitor's service life.
C24 = C29 = 220 pF. The bootstrap capacitor must be sized to have more than enough energy to drive the gate of the IGBT high without depleting the bootstrap capacitor more than 10%. A good guideline is to size CBOOT to be at least ten times as large as the equivalent IGBT gate capacitance (Cg).
The datasheet specifies a capacitor ratio of 10 between the DVCC (digital power supply) and VCORE pins. TI recommends using a 4.7-μF capacitor (minimum) at the DVCC pin. The TIDA-00472 reference design uses a 10-μF capacitor at the DVCC pin. A 0.1-μF capacitor has been added to obtain the best performance at a high frequency.
