Infineon Technologies AG announced that Hyundai Motor Company and Kia Motors Corporation have selected Infineon as supplier of power modules for their current hybrid car generations, the Hyundai Sonata Hybrid and Kia Optima. Hyundai and Kia teamed up with Infineon on the hybrid powertrain design including the Infineon HybridPACK 1 power module and the related control electronics as part of the electric motor inverter.
The HybridPACK 1 is a power module designed for mild hybrid applications for a power range up to 30 kW. Designed for a junction operation temperature at 150 °C, the module accommodates a six-pack configuration of 3rd generation Trench-Field-Stop IGBT (Insulated Gate Bipolar Transistor) and matching emitter controlled diodes and is rated up to 400A/650V.
It is based on Infineon’s IGBT Trench-Field-Stop Technology, which offers lowest conduction and switching losses.
HybridPACK 1 is suitable for air- or low-temperature-liquid-cooled inverter systems. The flat copper base plate combined with high-performance ceramic substrate and Infineon’s enhanced wire-bonding process provides optimized thermal cycling and power cycling reliability for mild hybrid inverter applications. For a compact inverter design the driver stage PCB can easily be soldered on top of the module. All power connections are realized with screw terminals.
Infineon’s HybridPACK 1 power module has a crucial role in controlling and powering the hybrid electrical motor as the energy bridge between the battery system and the HEV drive. The HybridPACK 1 is responsible to translate the direct current (DC) from the battery into alternating current (AC), which drives the electric motor, and from AC back to DC to charge the battery system using braking energy.
The Infineon HybridPACK 1 power module helps to reduce the physical size and weight of the inverter system, achieving the required power rating of up to 30kW while using up to 30% less semiconductor area compared to other available solutions. The performance of the power semiconductors used in the power module also contributes to a simpler cooling system for the inverter.
Infineon is also producing the HybridPACK 2, a power module designed for full hybrid applications for a power range up to 80 kW. HybridPACK 2 is rated up to 800A/650V.
Infineon produces its IGBT chips and emitter-controlled diodes for automotive power modules in Villach, Austria. The HybridPACK power modules are manufactured in Warstein, Germany.
