TangShan LingZhi Research Institute of High Voltage Power Supplyestablished at 1999 as a company. The company has its original patent for multivibrator type power conversion, and devotes the mind to study and develop high frequency and high voltage switching power supply. The products of the company can achieve the most advanced level even in China or abroad. The products can have extensive use in many domains such as power system, broadcast television, railway, radar, welder, lighting, non destructive radial test, medical apparatus, sea water desalination, and so on. The characters of the company adopted technique are: High reliability, low electromagnetic interference, high power density and high efficiency. This technique has been widely adopted by some world-class company such as: Vicor, Sony, Switchtech (New Zealan) and Sanken(Japan). The power developed by LingZhi-company for magnetron has achieve the high level in the top of the high voltage high density power supply domain. [
