Zusammenfassung:	The invention provides a system for a rapid short-circuit protection system for a direct current bus of an energy storage converter. Compared with a conventional short circuit protection structure based on a breaker or a fuse, the rapid short-circuit protection system for the direct current bus of the energy storage converter is based on a rapid cutoff capability of an IGBT (Insulated Gate Bipolar Translator), a power supply circuit can be cut off in hundreds of microseconds, and the safety of an energy storage battery and the energy storage converter is protected. According to the system, functions of all modules can be positioned clearly, the structure is compact, the installation and the debugging are facilitated, the response time of protection action is remarkably shortened, and the reliability of an energy storage converter system is improved.
