Abstract: this paper introduces the features and requirements of four high low electronic ballasts, the work done by the company in this field, list the production, the development of related species and the main index, put forward the proposal application. Keywords: high performance, low cost, the relevant circuit, application
a, high quality research and development of electronic ballasts, A) Electronic ballast is lit fluorescent tube power transformation and stabilizer, the market demand for it, namely the 'ideal' of the electronic ballast has the characteristics of 'four high and low' : 1, high reliability, use as far as possible do not damage in 5 ~ 10 years; 2, high standard, its security, the electric parameters of IEC, GB standards related to achieve the targets, CCC, CE, UL and other certification through; 3, high power: the power of several watts to several hundred watts of electronic ballast volume with power appliances for a fraction of a small percentage to or smaller, the internal temperature is higher than 75 ℃ or 90 ℃ ( Small lights) , than the average household appliances; 4, high anti-interference and protection function: the power grid, the natural lightning and tubes can have the function of self-preservation, and so on the damage of high frequency electromagnetic radiation and interference of power grids must be up to standard; 5, low cost, and the inductance ballast, incandescent lamp, such as contrast, should have certain comparability, only if the price and fairly or under the condition of no more than one to two times, a lot of use and promotion of electronic ballast will be widely accepted. Is more than five qualified electronic ballast, eliminate inferior product is fundamental! To make the electronic ballast it replaces a excellent results most or all of the inductance ballasts, produce remarkable economic benefit and social benefit. To achieve this purpose, we made some efforts in recent years, in the product development, production, promotion to do the corresponding work. Mainly for: 1) Seek, research and development to achieve 'four high' requirements are related to the electronic ballast circuit principle. To existing high performance IC VDMOS tube EB scheme and represented by line by flow, double pump circuit of the commonly used circuit, in view of the original rational reasons, the price is high, the latter part parameters can't improve, it is difficult to meet the requirements of 'four high and low', despite its high pump circuit indicators and cost are better, but the low efficiency caused by the principle of ( Electricity conversion efficiency eta = output/input power 0. % ( At the 'L') % standard ( 'L') 。 ( Power of 25 w or less 3 rd
