The key modules of the EMU auxiliary power supply system mainly include auxiliary converters, chargers, batteries and related loads. The topology of the auxiliary power supply system is shown in Figure 2. Figure 2. Topology diagram of the EMU auxiliary power supply system.
Abstract. In the modern world, when there is a power outage or a power failure, telecommunication systems, computer systems, and many other critical equipment, such as medical equipment, require uninterrupted power to support their operation. Uninterruptible power supply (UPS) systems are used for this purpose.
Uninterruptible power supplies provide power to critical loads in the event of a power failure. Unlike emergency generators, UPS systems provide power immediately, but only for a short period of a few minutes – until a backup power supply comes online or until the load completes its shutdown sequence.
High-speed EMU technology combines various complex technologies and the auxiliary power supply system is an important part of the EMU. It not only supplies power to all load devices outside the traction power system that need to be powered, but also ensures the normal operation of some parts of the EMU, which facilitates people’s lives and travel.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
