In 1997, Huangruilu founded Guangzhou Panyu Liaoyuan Electrical Appliance Factory.
In the early 1998, Liyuan started to produce high power silicon controlled rectifier of different sizes.
In 1998, the low power high frequency switching power supply was successfully made. At the same time, the silicon controlled rectifiers were widely used in the fields of plating, electroanalysis, electrochemistry, oxidation, electrophoresis, smelt and electroform, etc.
In 2000, Liyuan changed its name to Guangzhou Panyu Liyuan Electrical Appliance Factory.
In 2001, Liyuan brought in advanced technology and developed IGBT high power switching power supply.
In 2002, the intelligentized and digitalized networked control system of rectifiers was successfully developed.
In 2002, Liyuan became the No.1 brand in PCB plating industry.
In 2003, the high power high frequency switching power supply was successfully developed.
In 2004, Liyuan employed a group of high qualified people and founded Guangzhou Liyuan Electrical Appliance Co., Ltd.
In 2005, HK Liyuan Electrical Appliance International Co., Ltd was founded.
In 2006, Dongguan Liyuyuan Electrical Appliance Co., Ltd was founded.
In 2006, products of Liyuan got the certificate of CE.
In 2007, the super high power switching power supply entered the nuclear industry.
In 2006, Jiujiang Liyuan Rectifier Equipment Co., Ltd was founded in Jiujiangcheng Industrial Park in Jiangxi province.
Liyuan planned to transfer the production base of high power controlable silicon power supply and high power high frequency switching power supply to Jiujiang. Then, Jiujiang Liyuan Rectifier Equipment Co., Ltd will be the station for Liyuan to develop on the domestic market.
In 2006, the new factory in Jiujiang was put into use. Its total area is 30mu and the building area is 8000 square meters.
In 2007, rectifiers made by Lityuan entered the industry of top grade electroanalysis copper and foil.
In 2008, Liyuan established cooperation relations with some domestic colored metal groups, providing rectifier power supply.
In 2009, the first 50KA high frequency switching power supply in China was put into use in the industry of top grade electroanalysis copper and foil.
