In 2000, when more than 3,000 switchgear enterprises in China were still fighting fiercely, Chuangwei Zhang once again adjusted its course and turned to high-voltage frequency conversion speed regulating devices (that is, high-voltage frequency converters). This is an energy-saving product, which can adjust the speed of high-voltage motor and save energy. It is this turning point that enabled Yang Ming to complete the first transformation from power transmission and transformation equipment to the core technology of large-scale energy-saving and power electronic equipment.
In 2005, Chuangwei Zhang was entrusted to develop the control system of wind power generation equipment for other enterprises. After years of wandering in the energy industry, he keenly felt the huge development prospects of renewable energy equipment, especially the wind power generation industry.
With the sincerity of cooperation and the advantages of the product itself, in 2006, Mingyang Wind Power cooperated with German Aerodyn Company. It is reported that Aerodyn is a famous wind turbine design company in Europe with profound design experience. Mingyang Wind Power signed an agreement with the other party to jointly design and develop 1.5 MW wind turbines, and the intellectual property belongs to Mingyang Wind Power. In 2007, the prototype was made in Germany and passed the certification.
