Hi I am trying to make a Small fly back SMPS. I have two software for doing this. Viper soft for Viper22 and Power Int Software. When I give the same out put voltages and currents to both software, the calculation result seems to be much different. I can understand that both software uses different switching devices for SMPS. Is it possible that by changing the active device, it can cause huge change in transformer winding?

Viper Design is a leading provider of embedded software services, underpinned by years of experience from working with embedded control systems. App Development We specialize in providing comprehensive and scalable data solutions for your measurement, control, and logging needs.

Or something wrong with my procedure. (Vipersoft gives 160 turns primary whereas Powerint gives 60T the same core). Can there be that much difference in primary inductance in two circuits?

Software is good. Software is bad. And you can create a list of whys under both of those statements.

A problem with using a software package to do design work is that many times it is used blindly without knowing what it is doing. Software is someone's implementation of what he thought was the correct design process. It often makes assumptions and/or uses 'rules of thumb' but unless the software documentation clearly states those the user hasn't a clue and simply takes the results as a valid design. In the case you mention I would ask: 1. What design formulas does each SW package use?

What assumption about the design are made by each SW package? Are any 'rules of thumb' used by the SW? Av bros page curl pro 22 serial number. If so, what are they? Do they apply to what you are doing?

Do you know how to design the circuit without using the software or you blindly hoping it will make all the right decisions for you? Software design packages can be great aids for design especially where a lengthy complicated design process can lead to mistakes. However, unless they are well documented and understood by the user and verified for accuracy they can lead you down a primrose path. You might build up both SW design implementations and see which one works then at least you will have a better idea which is right or better.

The results are the needed capacitance value and equivalent series resistance (ESR) of the output capacitor. VIPer selection – step 2 1. Device selection: the software automatically selects the device based on the output power.

Operating mode: discontinuous mode is set by default but the user can change it to continuous. Maximum ambient temperature: has an impact on power dissipation, thus on the converter’s power capability. Case-ambient thermal resistance: the default value can be decreased and power dissipation improved by providing a heat sink. AC/DC input – step 3 1. Input voltage range selection: – 110 V range – 230 V range – Full range 2. Input ripple selection 3. Hold-up cycles selection 4.

Line frequency selection: 50 or 60 Hz Output inductance selection – step 4 In the inductor setting window, the user can change the default inductor by either choosing another inductor in a given database, or directly entering the inductance value, ESR, ISAT and parasitic capacitance of the custom inductor. The inductor is used for energy storage, and its selection depends on the output power and on the power switch. A custom ferrite inductor must be used in case of high output power converters. For low output power converters an axial insulated inductor can be used. The drawback of this low cost solution is the higher series resistance that could affect the efficiency of the converter.

The inductance value determines whether the circuit operates in discontinuous mode or in continuous mode for a given output current. Proshivka televizora panasonic tx lr32u3 3.
