SiC Intelligent Power Modules

Why

SiC-IPMSilicon Carbide (SiC) Power Transistors are now offering outstanding performances versus their silicon counterparts: Their low on-resistance at high blocking voltages, high switching speed and thermal performance allows system engineers to achieve significant gains in size, weight and efficiency for motor drives and battery chargers, in electric vehicles (EV) for example. The continuous drop in pricing is making SiC a mainstream technology. However, an important challenge for the adoption of SiC and other wide bandgap transistors in high power applications is the availability of well-optimized power modules as well as the learning curve in reliably driving them.

Intelligent Power Modules answer both challenges by offering highly integrated plug-in-play solutions accelerating time-to-market and saving engineering resources. Transitioning to SiC is a long journey that can be shrunk drastically by adopting our SiC Intelligent Power Module platform, benefiting from more than 10 years of expertise in the development of SiC power modules and gate drivers.

What

A 3-phase 1200V SiC MOSFET Intelligent Power Module platform integrating the power switches and gate driver based on the CISSOID HADES2® chipset.

These modules address high power density converters offering a SiC power module designed for operation at a high junction temperature (up to 175°C). This solution gives access to the full benefits of SiC technology to achieve high power density thanks to low switching losses and high temperature operation.

The integration of the gate driver together with the power module gives direct access to a fully validated and optimized solution in terms of switching speed and losses, robustness against dI/dt and dV/dt and protection of the power stages (Desat, UVLO, AMC, SSD, Anti-overlapping).

 The platform includes 3 modules with pin fin AlSiC baseplate for liquid cooling with different current rating allowing to find the best trade-off between cost, conductive and switching losses. It also includes a flat AlSiC baseplate module for applications where liquid-cooling is not an option.

Support for fast power converter design

SiC-IPMA great benefit of these IPMs is the high level of integration of the power module with its gate driver and AlSiC pin fin or flat baseplate. This allows a rapid mechanical integration with the other elements of the power converter such as the DC bus capacitor and the reference cooler as shown in the Figure on the right. The system designer may save a lot of time having access to an accurate a 3D model of the IPM including the gate driver right from the very start of development.

Power converter design is also supported with LTSpice models of the IPMs.
