[introduction]Input impedance, output impedance, it is so important that these two parameters are done not have it seems that, but the fact is not such. Next my views say below. Input impedance, output impedance, it is so important that these two parameters are done not have it seems that, but the fact is not such. Next my views say below.       A problem The coupling capacitance in frequency has from 0.1uF-220uF, is this sick? It is to use…

[introduction]In single-phase small-power smooth hot season and in network system, have segregation model attack with two kinds of blame segregation develop structure. Segregation have cost tall, volume is large wait for a lot of defect, because this is not segregation model become at present the develop of the mainstream attacks structure, the article basically introduces blame segregation model complete bridge and HERIC two kinds of relatively commonly used develop attack structure. In single-phase small-power smooth hot season and in network…

[introduction]MOSFET, IGBT and BJTSemiconductor deviceswitch speed gets the influence of the capacitance of component itself. To satisfy the efficiency of circuit, the architect needs to know these parameter. For example, design an efficient switch power source to will ask the architect knows the electric capacity of equipment, because this will affect switch rate, affect efficiency thereby. These information are offerred in the index manual of MOSFET normally. The switch speed of the semiconductor device such as MOSFET, IGBT and BJT…

[introduction]In consuming electronic industry catenary, white home appliance serves as indispensable important composition, long-term since the crucial role that acting quality of promotion dweller life. However, the product is coessential change, the market is added fast put delay, consumer energy-saving to home appliance product environmental protection and intelligence are changed wait for a function to hold what increase increasingly to expect, make industry of white home appliance for a time low fan. Face this situation, manufacturing industry of Chinese home…

[introduction]In going 10 years, automobile industry experiences most what revolution depends on software defining car is arisen. In traditional car design, be like,be aimed at the specific function such as dynamical assembly system or information entertainment system, all match subsystem of stock appropriative hardware. To satisfy the requirement that the model upgrades quickly, build modular, agile subsystem through compose (also call ” area ” ) will unite conformity a variety of functions, become more economy is efficient. Contemporary car is…

[introduction]Many pen paragraph type liquid crystal shows screen has static state and trends (scanning) means of two kinds of drive. When using static drive means, whole indication screen uses electrode of a communal back to be received give to cite a base, and each paragraphs of electrode needs to be received independently piece cite a base, if pursue 13, 29 are shown, the indication screen of means of drive of reason static state brings crural amount more. Introducing dynamic drive…
