Model order reduction as an integral part of e-mobility development process

Ever increasing power, efficiency and robustness requirements of electronic systems demand rising degree of co-operation between development partners. An obvious example is the e-mobility boom. It is essential to keep an eye on the complete chain of interactions from power electronics via magnetic to thermal, vibration, even acoustical domains during the complete development process from initial draft till final construction. Instead of exchanging complete virtual field models between domains, departments or companies involved an effective way is to exchange reduced order models. That allows protecting intellectual properties and establishes interaction options at the same time. In parallel the reduced order models allow the simulation of systems' behavior. In the paper presented methods are explained to reduce the field simulations' results into reduced order models. Examples are presented for structural, thermal and electromagnetic field reduction. This will show the role of reduced order models during the complete development process.
