High Voltage Intelligent Power Module Layout Design for Parasitic Inductance Reduction

When designing the high voltage intelligent power module, layout design is as important as circuit design. Appropriate layout design can avoid many problems associated with these types of power modules. This paper relates generally to the layout design of the power stage components within a 600V/30A high voltage SiC intelligent power module for low inductance. Several crucial aspects when designing the power stage layout have been pointed out. It also presents how to optimize the layout design to minimize the parasitic inductance.
