Where is the power module located in the BMW 4 Series?
1 Answers
BMW 4 Series power module is located under the trunk, which can be seen by opening the trunk. Introduction to power module: A power module is a power converter that can be directly mounted on a printed circuit board. As power supplies tend to be modularized and miniaturized, power modules have emerged. With the highest level of integration, the main circuit of the switching power supply is integrated into the chip, enabling functions such as wide-frequency modulation, isolation, and various protections. Function of automotive power module: It measures the difference between the actual output voltage and the nominal output voltage of the module. While achieving voltage conversion and power transmission, it also measures its own losses. It monitors the state of the output voltage establishment process or stabilization process when the power module is turned on.
