Abstract

The invention provides a railway vehicle charger system and a railway vehicle. The railway vehicle charger system comprises at least two sets of convertor components which are connected in parallel and connected through a communication bus, and output current of at least one convertor component is adjusted according to output current of other convertor components, so that output current of all the convertor components is maintained consistent. The railway vehicle charger system and the railway vehicle can solve the problems that an existing charger is large in size and low in intelligent degree, the size of the charger is reduced, and the intelligent degree is improved.

Description

technical field [0001] The invention relates to electrical control technology, in particular to a rail vehicle charger system and a rail vehicle. Background technique [0002] The operating system of a rail vehicle mainly includes a traction system and an auxiliary system, wherein the auxiliary system is used to supply power to auxiliary equipment in the rail vehicle, such as air conditioners, lighting, sockets, and ventilators. As an important part of the rail vehicle auxiliary system, the charger's main function is to convert the grid voltage into direct current, supply power for auxiliary equipment and charge vehicle batteries. The charger usually adopts a high-frequency soft-switching DC / DC converter. The higher the switching frequency, the smaller the output ripple factor and the smaller the volume of the charger. However, as the output power of the charger increases, the switching frequency will be limited and reduced, resulting in an increase in the output ripple fac...
