Abstract
The present invention discloses a distributed high-frequency AC electrical system for the electric vehicle. The system divides all loads of the electric vehicle into four load areas according to their spatial positions. Four high-frequency inverters and four DC input interfaces are contained in the system, with each of the four load areas being configured with one of the four high-frequency inverters, and each of the four high-frequency inverters being configured with one of the four DC input interfaces. One end of each DC input interface is connected to the DC side of the corresponding high-frequency inverter, and the other end is connected to the storage battery of the electric vehicle. Each high-frequency inverter outputs a high-frequency AC bus to supply power for the loads in the corresponding load area, and the four high-frequency inverters are in a parallel operation state through a high-frequency connection point that connects the four high-frequency AC buses. The present invention has the advantages of simplifying the electrical system structure of the electric vehicle, improving the system stability, and the like.
