Description

technical field

[0001] The invention belongs to the technical field of guide rail cars, and relates to a power unit, in particular to a highly integrated charger power unit. Background technique

[0002] With the rapid development of the city, the traffic pressure is increasing day by day. Because of the advantages of making full use of the existing urban roads, simple infrastructure, short construction period, low cost and no pollution, the urban guideway tram has broad application prospects. With the development of rail transit electric transmission technology, power units using high-power IGBTs as switching elements are increasingly widely used. In the prior art, one power unit only realizes one electrical function, and functions such as rectification and inverter are realized by multiple power units. .

[0003] However, multiple power units are installed independently, which not only increases the size and cost, but also has many interfaces, which increases the complexi...
