IGBT 杂散电感 电力电子
Measurement of the circuit stray inductance L The stray inductance of the commutation loop can be derived from the voltage drop across IGBT at turn-on: while the IGBT is still blocking and the current is already rising, you can measure di/dt and voltage drop ∆V and calculate the inductance according to Lσ = ∆V / di/dt
