| Abstract |
This paper deals with a low voltage, 400 W 20 kHz PWM MOSFETs inverter usable to feed variable speed drives in large distribution applications. The example of a motorfan for automotive has been chosen. Severe pressures of the application on cost and using conditions lead to main choices on machine and inverter structures with the aim of minimizing the number of electronic components and sensors for a later integration of electronics in the actuator. After a description of the variable speed actuator feeding structure and of inverter realization, emphasis is put on losses measures of high importance in such a low voltage application. A calorimetric method is used, which allows to separate conduction and switching losses. The main importance of conduction losses is outlined. |
