The diode pump entire solid state laser's mains input is big, outputs for the big ... -
Based on soft switch technology DC/DC power transformer’s design - 51RD Chinese electronic net
Saturday, January 31st, 2009 at 10:53 | No commentsCategories: Power SupplyShort Content: O introduction Based on soft switch technology entire bridge 0C/DC converter in high frequency, high efficiency direct-current transformation domain, has the widespread application prospect, it raised system's efficiency, has increased the installment power density. This article designs the converter right now applies in the electronic simulation power termination, this load system request can realize the energy back coupling electrical network effectively, and direct-current high pressure >540V, the low pressure cocurrent is 48~60V, therefore, is the pressure-rise transformation. As space is ... -
One kind of practical BOOST electric circuit
Saturday, January 31st, 2009 at 05:53 | No commentsCategories: Power SupplyShort Content: 0 introductions Will involve frequently in the practical application to boosted circuit's design, regarding big power output, if 70W above DC/DC boosted circuit, because the special-purpose pressure-rise chip interior switching valve's limit, will difficulty with achieve the high efficiency pressure-rise transformation, moreover the chip price will be expensive, when practical application will receive the very big limit. Considered the Boost pressure-rise structure external connection switching valve choice leeway is very big, chooses the appropriate control chip, then may design the ... -
Is advantageous for integrated the intellectualized power source module supervisory system research
Saturday, January 31st, 2009 at 00:53 | No commentsCategories: Power SupplyShort Content: 0 introductions Along with the electric power electronic technology's fast development, the switching power supply receives more and more takes seriously, particularly in the correspondence, the electric power domain obtained the widespread application. In recent years, to enhance the conveniences which and the simplicity the power source used, power source's modulation and the integrated into research important topic. The power source uses the modular design to cause the different system to be possible to act according to own capacity to ... -
The frequency multiplication type IGBT high frequency induction heating power source load short-circuits protection
Friday, January 30th, 2009 at 19:53 | No commentsCategories: Power SupplyTags:Short Content: O introduction Insulation grid double pole transistor ICBT (Insulated Gale Bipolar Translstor) is one kind of component which bonds by MOSFET and the double pole transistor becomes, its input extremely MOSFET, output extremely PNP transistor, therefore, it both has the MOSFET component to actuate simple and the fast merit, and has the double pole component capacity major characteristic. These merits enabled IGBT to obtain more and more widespread application in the modern electric power electronic technology. Uses IGBT to take ... -

Active control white light LED electric current switch manostat
Friday, January 30th, 2009 at 09:53 | No commentsCategories: Power SupplyShort Content: Several years ago, manufacturers also white light LED, but is not the gloomy LED most Taisho to the nominal current hypothesis is 20 mA. Today's white light LED may provide a higher brightness, must therefore work under the higher bias electric current. Must maintain to in the close LED most large quantity definite value's big electric current working condition a LED bias control, needs one new method. Of the bias LED simple, the most commonly used method is connects a ... -
Based on TOPSwitChⅡThe single end instead stirs up switching power supply’s modelling and the dynamic analysis
Friday, January 30th, 2009 at 04:53 | No commentsCategories: Power SupplyTags:Short Content: O introduction Switching power supply by its small, featherweight and high efficiency characteristic, but widely is applied in by the electronic juice calculated that machine for in the leading each kind of terminal device, the communication facility, is now an electronic information industry swift development essential link, but switching power supply performance fit and unfit quality also direct relation overall system's security and reliability. The switch voltage-stabilized source has many kinds of types, the single end instead stirs up-like the ... -
Switch voltage-stabilized source
Thursday, January 29th, 2009 at 23:53 | No commentsCategories: Power SupplyTags: Switching power supplyShort Content: 0 introductions After the switch voltage-stabilized source (hereafter refers to as switching power supply) comes out, in many domains gradually has substituted for the linear voltage-stabilized source and the thyristor controls the power source. What the early time appears is the series switching power supply, its main circuit analysis situs and the linear power source are similar, but power transistor work on-off state. Along with the pulse-duration modulation (PWM) technology's development, the PWM switching power supply comes out, its characteristic ...
