LingZhi institute of high voltage power supply was founded in 1999.The institute has its original patent of LLC resonant converter,and devotes the mind to study and develop high frequency and highvoltage switching power supply. The products of the company canreach the most advanced level in China even abroad. The productscan have extensive use in many domains such as power system,broadcast television, railway, radar, welder, lighting, nondestructive radial test, medical apparatus, sea water desalination,etc. The character of our technology: high reliability, lowelectromagnetic interference, high power density and highefficiency. This technology has been widely adopted by someworld-class company such as: Vicor, Sony, Switchtech (New Zealand)and Sanken(Japan). The power module developed by LingZhi institutefor magnetron has reached the top level in the high voltage powersupply domain. Our institute would like to offer our high qualified power supplyto all the friends and to cooperate with you sincerely.
