Wednesday, May 27th, 2009 at 03:59 | No commentsCategories: SCMShort Content: 1 introduction The automobile bussing technique is one of field bus's applications, the initial field bus only uses in the industrial control. The so-called field bus is the application in the production lowest level one kind always the linear analysis situs network. The automobile body directed net needs to solve at present the question is establishes a unification, the low cost low end communication network standard, LIN exists as the CAN auxiliary main line, realizes the automobile body directed net ... -
The liquid-crystal display power source manages circuit design
Thursday, May 7th, 2009 at 22:07 | No commentsCategories: Power SupplyShort Content: 1 introduction Must realize the liquid-crystal display to demonstrate that must have the following 4 units: Controller (Controller), power source management unit (PMU), driving circuit (Driver), liquid crystal display component (LCD). Regarding the resolution small liquid crystal display component, like 128×64, 128×32 and so on modules have controller, the power source management unit, the driver in a body's chip. But regarding the high resolution's liquid-crystal display (for example 320×240, 640×480) needs independent controller, the power source management unit, the ... -
The high efficiency bit - 48V inserts hotly pulls out the controller design
Saturday, April 25th, 2009 at 06:00 | No commentsCategories: Power SupplyShort Content: Many large-scale telecommunications and the data communication systems use insert on common back board many circuit wafers or the bit construct to the rack. The back board as well as between them the correspondence provides the power source for the bit (e.g. - 48V, 12V). Because the back board power source is at the opening condition throughout, therefore is called "hot" or "is moving" the back board. The bit must insert the rack, but cannot affect on the ... -
The motor control uses the low power voltage-stabilized source’s design
Wednesday, April 15th, 2009 at 10:59 | No commentsCategories: Power SupplyShort Content: Abstract: Not brushes the direct current machine control system's need in view of 170W, designed has instead stirred up-like the auxiliary switch voltage-stabilized source based on TOP224Y. This power source for controller's pulse-duration modulation chip, the logical synthesis chip as well as the actuation chip provides the multi-channel output service voltage, and has realized the isolation. Introduced with emphasis instead stirs up-like converter's key job principle, has analyzed three end off-line type PWM the integrated chip TOP224Y characteristic, based on ... -
Uses the fixed breakover timer to optimize switching power supply underloading energy efficiency - 51RD the Chinese electronic net
Tuesday, April 7th, 2009 at 19:08 | No commentsCategories: Power SupplyShort Content: Because has the high efficiency and the high power density, switching power supply's is getting more and more popular in modern electron system use. Specially along with the control chip's application, switching power supply's circuit design obtained the enormous simplification, often only needs in the pulse-duration modulation (PWM) control chip foundation to add some periphery component then to compose the switching power supply again, this even more promoted switching power supply's design and the development. Looking from the type, the ... -
Static transforms aviation ground supply PWM voltage regulator’s design
Tuesday, February 10th, 2009 at 16:02 | No commentsCategories: Power SupplyTags: aviation ground supply, controller, logic programming, static transforms the, The pulse-duration modulation, voltage control systemShort Content: Abstract: Some airplane ground special-purpose power source uses voltage control system use "switchpoint initialization adjustable pulse width control technology" the entire digitized PWM control mode, has the automatic accent pressure, functions and so on fail safe and soft start. In the article introduced the voltage control system's principle of work and realizes the electric circuit. Key word: Pulse-duration modulation controller logic programming 1 introduction At present, in the converter uses the pulse-duration modulation control technology mainly has ... -
Manages power source’s simple method by the digital form
Friday, February 6th, 2009 at 06:53 | No commentsCategories: Power SupplyShort Content: The high usability power source's digital management has the future greatly, but this kind of digital management is frequently take uses the high cost the complex multi-chip electric circuit solution as the price. For example, has the voltage/electric current surveillance and the power source allowance control application possible need many integrated circuit, like the low drifting datum, the resolution are at least 12 multichannel differential input ADC, 8 DAC and the special-purpose micro controller. In addition, realizes the allowance ...
