On July 16, the CR200J-D Fuxing bullet train, produced by CRRC Puzhen Company, was launched in the management of Chengdu Bureau Group Company for the first time. Nanjing Huashi Electronic Technology Co., Ltd. provides air conditioning inverter power supply and bus charger for the car, providing a solid guarantee for the smooth operation of the train and the comfortable experience of passengers.

The CR200J-D Fuxing EMU has a single group of 236.7 meters long and consists of nine units, with a maximum running speed of 160 kilometers per hour. It is suitable for high altitude, multi-tunnel, large ramp and other environments, and has the advantages of ultraviolet light resistance and low temperature resistance, so it is called the "plateau version" Fuxing EMU.

As one of the core components of the EMU power system, the stability and efficiency of the bus air conditioning inverter power supply provided by the company are directly related to the ride experience of passengers. With years of technical accumulation and research and development experience, the company's research and development and manufacturing of inverter power in the conversion efficiency, stability, safety and other aspects have reached the industry leading level. At the same time, the product also has the function of intelligent monitoring and fault self-diagnosis, which can monitor the running state of the power system in real time, to ensure that the abnormal situation can respond quickly and take measures, effectively guarantee the safe operation of the EMU.

As an important part of the auxiliary power supply system of the EMU, the bus charger mainly charges the on-board battery and supplies the DC load of the car. Using phase shift full bridge flexible switch technology and DSP digital control technology, it can realize a fast, efficient and stable charging process. At the same time, the product also has multiple safety protection measures such as over charge protection, short circuit protection and over voltage protection, effectively avoiding safety accidents caused by improper charging.

With the continuous development of China's railway industry, the Fuxing EMU will play an important role in a wider range of fields and at a deeper level. As a member of the field of railway equipment in China, Huashi Company will continue to uphold the enterprise spirit of "innovation, pragmatism, efficient and win-win", constantly increase r & d investment and technological innovation, to provide more high-quality, efficient and safe equipment products and services for the railway industry.
