IGBT IPM Intelligent Power Module Diode and Junction Test Procedure using a DMM.
Single Pack IPM IGBT Powerex PM600HSA120 & similar Intellimod IGBT Bricks:
Meter on Diode Test Mode
BLK to C, Red to E = 0.5v +/-, swap = OL
Meter on Resistance Mode (Ohms)
E to Pin 4 = 0 Ohms
Dual Pack IPM IGBT Powerex PM300DSA120, PM200DSA120 & similar Intellimod IGBT Bricks:
Meter on Diode Test Mode
BLK to C1, Red to E1 = 0.5v +/-, swap = OL
BLK to C2, Red to E2 = 0.5v +/-, swap = OL
Meter on Resistance Mode (Ohms)
E1 to Pin 4 “P” = 0 Ohms, E2 to Pin 4 “N” = 0 Ohms
6 Pack IPM IGBT Powerex PM150CVA120 & similar Intellimod IGBT Bricks:
Meter on Diode Test Mode
BLK to P, Red to W = 0.5v +/-
BLK to P, Red to V = 0.5v +/-
BLK to P, Red to U = 0.5v +/-
Swap Leads = OL
BLK to W, Red to N = 0.5v +/-
BLK to V, Red to N = 0.5v +/-
BLK to U, Red to N = 0.5v +/-
Swap Leads = OL
Meter on Resistance Mode (Ohms)
W to Pin 2 = 0 Ohms
V to Pin 6 = 0 Ohms
U to Pin 10 = 0 Ohms
N to Pin 15 = 0 Ohms
*Note: Testing the Diode portion of a 6 Pack IGBT is the same as testing a 3 phase rectifier.
If using Resistance Mode (Ohms) to test the Freewheel Diodes you should read over 100k (100,000) Ohms one way and read Open OL when you swap meter leads.
Any shorts or opens on diodes or opens on gates indicates a defective IGBT.
