Infineon Technologies has launched an IGBT power module for electric vehicle traction inverters in the 80 kW to 100 kW power class.
The HybridPACK DC6i six pack module is optimized to deliver an excellent fit of system cost and performance to hybrid and small battery electric vehicles. It combines Infineon’s established EDT2 IGBTs with package technologies for compactness, very good thermal management at reduced material cost, and an easy installation.
The global boom of vehicle electrification puts the design of cost-effective traction inverters into focus. In this context, selecting the power module plays an important role; system designers are looking for the best-sized module with the optimal silicon area for the required performance. The HybridPACK DC6i is positioned between the HybridPACK1 family and the more powerful HybridPACK Drive family.
The new module has the same compact footprint (7.2 cm x 14 cm) as the HybridPACK1 – 25 percent smaller than the HybridPACK Drive – but the available output power is more than 50 percent higher. While the HybridPACK1 uses Infineon’s IGBT3 technology, the HybridPACK DC6i is equipped with the latest EDT2 IGBTs.
The new module also has six screw connectors to the DC-link capacitor compared to two in the HybridPACK1 family. This enables a low-inductive design with a stray inductance of 15 nH. A patented direct-cooling wave baseplate provides heat dissipation with a thermal resistance from the IGBT chip junction to the fluid of 0.17 K/W.
The DC6i was designed for automated high volume production with Press-Fit pins and additional guiding elements enable gate driver board mounting in a few seconds compared to traditional selective soldering in more than one minute.Infineon’s EDT2 technology is an automotive micro-pattern trench field-stop cell design optimized for electric drivetrain applications. It offers a blocking voltage of 750 V, a short-term extended operation temperature of 175°C and high short-circuit ruggedness. The design tradeoff between switching and conduction losses is optimized for a real-world driving cycle with excellent light
