Abstract：Economic development is getting better and better， and people’s quality of life is also constantly improving. Following this， the urban transportation industry is also changing rapidly. Rail trams are gradually being operated， and at the same time， they are correspondingly used in rail transportation. The auxiliary inverter is a very important part. It can not only provide the vehicle with lighting， air conditioning， etc.， but also allow the low-voltage equipment of the vehicle to provide the required power， so that the electric bus can run more smoothly and smoothly. However， there are still some shortcomings in its technology and system in its actual application. In view of the existing problems， the relevant units should pay attention to rigorous analysis and discussion， find suitable ways to adjust them， make reasonable judgments on the auxiliary inversion system and power supply technology they use， and make the systems and Technology can be further improved to reduce the probability of problems and also promote the rapid development of the industry.
