They can be widely used in many high-energy consumption industries such as metal surface treatment (oxidation, electroplating, coloring, electrophoresis), non-ferrous metal smelting and purification (lead, zinc, copper, manganese, etc.), special gas electrolysis, copper foil/aluminum foil formation, harmonic management, electric vehicle (passenger vehicles, site vehicles) charging, electrochemical energy storage, induction heating, rail transit, communication and other high-energy consumption industries.

Yishite Group (stock code: 300376) was founded in 1989 and successfully listed on the Shenzhen Stock Exchange in 2014. It is now a model of mixed ownership of listed enterprises and state-owned enterprises under the Guangdong Provincial State-owned Assets Hengjian Holdings. Yishite Group ranks among the top 500 new energy companies in the world and the top 100 innovative enterprises. It is currently the first brand among domestic photovoltaic inverters, wind energy converters, solar photovoltaic power generation systems and comprehensive energy solutions manufacturers. It is a key high-tech enterprise in the National Torch Program, a national technological innovation demonstration enterprise, and a national intellectual property demonstration enterprise. It has won the "National May 1st Labor Certificate". It has 268 marketing and service centers around the world, covering more than 100 countries and regions. The company mainly engages in three strategic businesses: 5G+ smart power supply (UPS/EPS power supply, 5G base station power supply, rail transit power supply, military power supply), big data (cloud computing/edge computing data center, IT infrastructure), smart energy (photovoltaic inverters, wind energy converters and power generation systems, lithium batteries and energy storage systems, charging pile modules and systems, microgrids and smart distribution networks). It is a global digital industry & smart energy comprehensive solution provider.

The company's technical team is composed of professors (doctoral supervisors), electronic control experts and senior engineers from Zhejiang University, South China University of Technology, and Southwest Jiaotong University. It has more than ten years of product research and development experience. The company's core technical team has long been committed to the research and development of high-efficiency power conversion, and has undertaken a number of scientific research projects in the field of high-frequency power conversion by the country, province and city. Breakthrough progress has been made in the reliability, safety, harmonics, efficiency, process adaptability, system thermal design, EMC design and TB rectification of high-frequency industrial power supplies. We have successively successfully developed high-frequency energy-saving oxidation, electroplating, electrolysis, electrophoresis and other series of electrical energy conversion equipment based on fully digital soft switch control. Breakthrough progress has been made in power device driving and protection, new circuit topology research and application, digital control systems, advanced control strategies, device and module series and parallel control, harmonic processing and power factor correction, synchronous rectification, thermal design and electromagnetic compatibility design, etc., forming a deep technical accumulation, and obtained more than 20 national authorized patents, forming a patent group for high-efficiency, energy-saving, high-power, high-frequency power and high-frequency power products.
