Robert Bosch, Computer Simulation Technology AG and Berlin's Technical University are jointly developing a software package to test energy-efficient power electronics.
The project may help the electric-vehicle industry lower costs and speed up development of key technology inside the car.
The so-called SOlar project - a German acronym for simulation and optimization methodology for the system design of power electronics - wants to design a system that lets engineers identify electrical and thermal problems with computer software.
Power electronics such as direct-voltage and other converters, battery chargers and infeed units assure the conversion of electrical energy with 99 pc efficiency, the research cooperative said in a press release. "That's a precondition for sustainable mobility - in the electrification of vehicles - and for the efficient use of regenerative sources of energy."
Power electronics are difficult to design because they not only need to perform but also have to meet requirements for power density, longevity and electromagnetic compatibility. The auto industry then wants the components to be as small as possible, which further complicates the design.
The project engineers said that this complexity makes it virtually impossible today tosimulate how different parts of a power electronics system interact with each other.
The goal of the SOlar project is to change this situation by building a software package that lets engineers quickly and cost-effectively study how positioning and design of a component affects circuit functions, thermal characteristics and electromagnetic compatibility.
Robert Bosch is the world's largest automotive supplier. CST is a maker of high-performance simulation software. Germany's Ministry of Education and Research has provided a 1.4 million euro grant for the SOlar project.
