Development of a 450A/600V 6-in-1-package intelligent power module (IPM)

Intelligent power module (IPM) has been increasingly used in power electronics converters due to its high integrity and high reliability. The proposed IPM is based on an IGBT module named GD450HTT60C7S which has power ratings of 450A/600V. This paper deals mainly with the packaging process and the protection characteristics tests of a 450A-600V 6-chips-in-one-package IPM. The IPM has multiple protection functionalities including under-voltage protection, over-current/short current protection and over-temperature protection. The threshold value of each protection features can be adjusted during the design stage according to application. The control-interface of the IPM has adopted the currently-popular square-cross-sectional pins in which high-voltage drive sources and the low-voltage PWM signals are separated to reduce EMI. The experimental results verified that the IPM module has highly reliable protecting features.
