The functions of the J-IPM and N-IPM are identical, and the protection functions against short circuit, overcurrent, drive power supply under-voltage and overheating are integrated. However, since both the J-IPM and the N-IPM are constructed of many types of electronics parts, there are of course some limits to downsizing and low price. To protect against overheating the temperature of the insulation substrate mounted with the IGBT chips was detected by thermistors. But it became problematic in applications where the current was concentrated into a few chips like motor lock mode, as shown in Fig. 1.
