    NPC Inverter Boost IGBT Zener Clamp

    I just want to know what is the significance of each of the parts is because when i looked up the datasheet, i can't understand how they were able to come up with the values for the boost inverse diodes.  Looking at it, it is a zener clamp.  Now, I am assuming that the specified voltage drop in...

    NPC Inverter Boost IGBT Zener Clamp

    Attached is the datasheet for the circuit I am talking about.  I just want to know how they were able to determine the values for the boost inverse diode (diode clamp). Thanks, Law FZ06NPA070FP-P969F-14.pdf
