Frequently Asked Questions
How do I calculate the snubber capacitor value for IGBT protection?
Snubber capacitor C = L × I² / V², where L is stray inductance, I is peak current, V is allowable overvoltage. For typical 1200V IGBT with 100A current and 1μH stray inductance: C = 1×10⁻⁶ × 100² / (200)² = 250nF. Use 200-300nF standard value.
Calculate based on stray inductance and peak current, then select standard value.
