This paper presents a methodology for choosing the optimal PWM method for the 3-phase automotive drives applications for electric and electro-hydraulic power steering. It shows how some of the automotive specific requirements transpose to PWM requirements. A system overview with motor and control principles has been presented, followed by the method of power loss calculations based on datasheet parameters and, after that, an overview of the PWM Methods is given. These Methods are compared based on: power loss minimisation, usage of the battery voltage, quality of output current and noise emission minimisation.

Reducing the quantity of CO2 emitted by automobiles is becoming an increasingly important concern — one that will cause automobile development and manufacturing costs to rise. High CO2 emissions will also create additional costs for car buyers, as policymakers begin taxing CO2 and auto makers pass on to consumers the costs of CO2 trading certificates and CO2 penalties. In this article, Infineon shows how a realistic and commercially viable reduction in CO2 output of around 20g per kilometer can be achieved by incorporating demand-based control into a small number of automotive applications.

CO2-Reduktion bei Kraftfahrzeugen spielt eine immer wichtigere Rolle und wird zu einem Anstieg der Herstellungs- und Entwicklungskosten fuhren. Andererseits fuhrt ein erhohter CO2-Ausstos zu Mehrkosten beim Kfz-Kaufer, etwa durch CO2-Besteuerung, aber auch zu Mehrkosten beim Fahrzeughersteller, beispielsweise durch CO2-Zertifikatehandel oder Ausgleichszahlungen. In diesem Beitrag zeigt Infineon, dass mit Hilfe einiger weniger, bedarfsgerecht gesteuerter Applikationen eine realistische und kommerzielle CO2-Reduktion von rund 20 g CO2/km zu erreichen ist.
