摘要

With the development of electric drive technology, electricity have gone into transportation. Not only can electric meet the needs of the loads of a vehicle itself, but also can it serve as a form of interconnection between different devices. Electricity can also be applied to special vehicles. This paper first analyzes and explains the overall structure of the system of a special vehicle, and establishes a simulation model of the vehicle. Subsequently, this article simulated the stability of the system under two operating conditions, and simulated the short-circuit current of the system based on a specific example. The results show that the system can maintain stability well for the transducers and control strategies used in the paper, and the simulation output results are in agreement with the real vehicle results.
