Dual-side cooled novel IPM and improved capability of inverter for elevated-temperature operations

Novel two-side cooling for integrated power modules (IPM) is developed for elevated-temperature operations. This approach applies and improves commercially off-the-shelf (COTS) products of IPM without significantly changing the original packaging design and manufacture´s fabrication process. It can reduce the p-n junction temperature rise of the power devices inside by 20% at an equivalent load, thus increasing operating ambient temperatures, which is desirable for integrated motors and elevated-temperature applications. The size and volume associated with conventional cooling mechanism can be shrunk. DC-link capacitor reduction with adaptive PWM control is also discussed
