Hybrid electric vehicle EV/HEV inverter design

As our components continue to deliver cost-effective, high efficiency and high power density, Infineon is also driving electric system solutions for future personal mobility. The mobility of modern lifestyles is increasing, increasing CO2 emissions and natural resource consumption. Personal transportation is moving in the direction of future mobility with lower emissions than today.

Moreover, rising oil prices and government regulation are also creating new border conditions that will accelerate the introduction of electric vehicles (EVs). Emissions regulations on both sides of the Atlantic are increasing penalties for automakers that do not meet fuel efficiency or emission standards.

In fact, we have found a significant shift in consumer demand in the direction of more fuel-efficient cars. Demographics also play a role, as more and more people will live in large cities, which further increases the demand for electric vehicles.

Considering that future emission standards will be more stringent, the only way to achieve this is to introduce zero-emission vehicles; this can only be achieved by developing emerging technologies such as all-electric steamboats or hydrogen fuel cell vehicles.

In the future, it is highly probable that different technologies will coexist; for example, high-performance batteries that store electrical energy, fuel cells that generate electricity, and supercapacitors that meet the sudden increase in energy demand. Infineon can take advantage of this trend by expanding its electric drivetrain activities, such as hybrid electric vehicles.

Electronic components are the key to improving energy efficiency. In order to save energy and reduce pollution, Infineon offers innovative high-performance solutions using the best (hybrid) electric vehicle technology of its kind, which represents one of the most efficient energy-transfer methods for personal transportation.

Infineon combines the expertise of the world's leading power electronics and the world's second largest automotive semiconductor company to deliver innovative electronic solutions for these new personal transportations. These solutions continue our commitment to excellence in quality and reliability, which is what the world's leading light vehicle manufacturers expect.

Our system expertise means that we can provide a comprehensive chipset to achieve the best balance of performance and cost. Today, we are pleased to offer our customers technology-leading products in many areas of HEV applications such as power semiconductors, power modules, microcontrollers and sensors.
