Abstract
A rotator position sensor is required for brush-less direct current motor (BLDCM). The sensor reduces the system reliability and makes it expensive. For fuel pump motor, there is nearly no space to install the position sensor and it is very difficult and costly to do this work. Therefore, a sensor-less control method is required in fuel pump application. This paper introduces a new fuel pump driver using Infineon Embedded Power ICs (ePower). It integrates a back electromotive force (BEMF) comparator, and it can provide the rotator position information. The test result shows that ePower is a very smart powerful IC, and the driver based on it can fully handle the fuel pump perfectly.
