如要应对提高燃油效率、减少二氧化碳排放和提高车辆可靠性的挑战,需要查看可能导致能量损耗的各种来源,重新思考构建相关子系统的方式。因此,由于电动燃油泵有助于减少液压摩擦造成的损耗,它们正逐步取代机械系统。

电动燃油泵通常采用无刷直流(BLDC)电机进行驱动。ST提供一整套三相栅极驱动器和功率MOSFET为其电机供电。SPC5 32位汽车微控制器以及专用的调压器和电源管理IC简化了高效解决方案的设计过程。

    • Based on the EVAL-L99ASC03 evaluation board designed for sensorless 3-phase BLDC motor control, the system features enhanced power management power supply functions including various standby modes. The motherboard, based on an STM8 microcontroller, provides the logic section for monitoring and driving the L99ASC03G 3-phase motor pre-driver assembled in the daughterboard. 

      ST also provides dedicated user-friendly software with a Graphic User Interface (GUI) that enables the user to set L99ASC03G parameters while displaying device information in real time.

      Developers can easily evaluate their brushless DC motor control solution for a variety of circulation and booster pump applications for coolant, water, fuel or oil lines.
