10.2.1.2 PVCC Capacitor Recommendation

The large capacitors used in conjunction with each full-bridge, are referred to as the PVCC Capacitors. These capacitors should be selected for proper voltage margin and adequate capacitance to support the power requirements. In practice, with a well designed system power supply, 100 μF, 16 V will support most applications with 12-V power supply. 25-V capacitor rating is recommended for power supply voltage higher than 12-V. For The PVCC capacitors should be low ESR type because they are used in a circuit associated with high-speed switching.
