To make good use of such a great opportunity , we are preparing for 3000 m2 area for a new factory , to build 6 more production lines for ferrite cores and 50 more production lines for transformers . until 2010 , when everything is ok , the total capacity of ferrite cores and transformers will be as twice as right now . copyright 2005 haining lianfeng magnet industry co . , ltd 为抓住软磁铁氧体工业蓬勃发展的大好机会，公司在盐官镇郭店工业区新征土地30000平方米，新建6条氮窑生产线和50条电子变压器生产线，至2010年，项目全部投产后，软磁铁氧体磁芯和电子变压器生产规模将在现有基础上翻一番，相当于再造一个联丰磁业。
The shanghai leishi lighting co , . ltd is a collection of research , development , production , marketing , “ green lighting appliances , ” which integrated modern enterprises , the company ' s electronic energy production , electronic ballast and electronic transformers , tongdeng , low voltage supply , the grid supply , jinludeng , such as light - series of products , product quality have reached the international advanced level , and widely used in hotels , shopping centres , hotels , office off as , residential lighting and other projects 上海雷士照明有限公司是一家集研究、开发、生产、销售“绿色照明电器”为一体的现代化型企业、公司生产的电子节能灯，电子镇流器和电子变压器，筒灯、低压射灯、格栅射灯、金卤灯、光源等系列产品，产品质量均已达到国际先进水平，并广泛应用于酒店、商场、宾馆、办公场所、住宅等照明工程。
The prototype test results indicate : voltage mode and current mode ac - ac mode ac / ac converters with high frequency link have the advantages such as high frequency electrical isolation . simple topology , two - stage power conversions , high power density , bidirectional power flow , good line current waveform , no audio noise , high converting efficiency , and high input power factor etc . this kind of converter lay the key technical foundation on new type regulated sinusoidal ac power supply , electronic transformer , ac regulator , and wave converter etc 试验表明，这类变换器具有高频电气隔离、电路拓扑简洁、两级功率变换( lfac hfac lfac ) 、功率密度高、双向功率流、无音频噪音、变换效率高、网侧功率因数高等优点。为新一代正弦交流稳压器、电子变压器、交流调压器、同频波形变换器的实现奠定了关键技术基础。
