Hybridpack Drive – Modular Power Semicondcutor Solutions For EVS

E-MOBILTY – MAIN INVERTER MARKET TRENDS

Worldwide, the hybrid and electric vehicle (xEV) market is growing exponentially, showing the highest growth rates in the automotive sector for decades. This market trend is mainly driven by legislation on the reduction of emissions. Many upcoming standards will not penalize CO2 emissions of individual vehicles, but that of the entire fleet sold by an OEM. The European Union, for example, has set a limit of 95 g/km fleet average from 2021 and will reduce it to 59 g/km by 2030. As a result, car manufacturers need to electrify a wide range of vehicles – from small city cars to large long-range sedans and SUVs. OEMs and Tier 1 suppliers need scalable and cost-efficient solutions to meet those ambitious targets.

Infineon supports system suppliers with the widest product portfolio of power semiconductor solutions for xEV main inverters in the industry – ranging from chips to discrete solutions and entire modules. At the heart of Infineon’s xEV module portfolio stands the HybridPACK™ Drive. The lead product was introduced in 2017 and is now complemented with an entire product family 1 & 2. This power module family provides power scalability between 100 kW and 175 kW and an easy design-in concept to support Tier 1 suppliers and automotive OEMs in the development of a cost-effective platform approach for main inverters.

Adding to the spectrum, Infineon also introduced a 1,200 V Silicon IGBT chip in this product family, enabling higher vehicle working voltages necessary for fast charging purposes with battery voltages of 700 V or more. The demanding requirements of commercial, construction and agriculture vehicle (CAV) applications like buses and trucks can also be met. In a next step, the family will also implement Silicon Carbide chip technology, which achieves a doubled power density compared to Si based devices.

Sound Generation For Enhanced Road Safety

With an ever-increasing number of fully electric and hybrid vehicles entering the market, we are witnessing a change in the acoustic experience in and around the car. The silent nature of the electric powertrain means that other road users miss the familiar acoustic cues that warn them of an approaching vehicle. To remedy this situation, Harman is working on various noise management solutions.

OBJECTIVE ASSESSMENT OF THE SAFETY CONTRIBUTION OF TODAY'S AUTOMOTIVE HEADLAMPS

Good lighting makes a major contribution to road safety. In 2011, the International Commission on Illumination (CIE) presented an evaluation system for headlamps that can objectively assess the quality of illumination and glare limitation. New light sources like LEDs and lighting functions (glare-free high beam, partial high beam) have been available for several years, so that an extension of the proven CIE method is necessary, which takes into account, among other things, changed switch-on and service lives of new lighting functions and represents a generally understandable evaluation system. An evaluation system presented in the following by the Technische Uni versität Darmstadt, which was developed by an encompassing expert commission, is intended to provide representative data and enable an objective evaluation of headlamp performance.

FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT

Increasing levels of electronic content in vehicles result in a large amount of software that is required to run the scenes behind the mechanical aspects of a vehicle. Electronic systems in automobiles are part of every section, from the powertrain to comfort and convenience systems as well as all types of safety equipment. This makes electronics and the software running these systems a critical part of the equation for future mobility solutions. In addition, putting standards in place to measure methods of developing, testing and functioning of such electronic systems also becomes highly relevant.
