SKYPER™ 32 R
External Boost Capacitors (BC)
The rated gate charge of the driver may be increase by additional boost capacitors to drive IGBT with large gate
capacitance.

Dimensioning of Cboost
ƒ Cboost15P [µF] = QGE [µC] × 1/V - 2,2µF
ƒ Cboost8N [µF] = QGE [µC] × 2/V - 4,7µF
ƒ QGE: Gate charge of the IGBT @ VGE = -7 …+15V
ƒ Minimum rated voltage Cboost15P: 25V
ƒ Minimum rated voltage Cboost8N: 16V
ƒ Type of capacitor: ceramic capacitor
Please consider the maximum rating four output charge per
pulse of the gate driver.
Application Hints
The external boost capacitors should be connected as close as
possible to the gate driver and to have low inductance.
