## Sw for simulating RF current transformer and ceflected wave?

Any RF simulator can run for transformers.Since the transformers are passive components, any kind linear RF simulator will serve you.

## CST-Microwave studio- transformer simulation

Hi, I want to simulate a power transformer in CST-microwave studio. pls help me..

## Questions about datasheet of transformer(Wurth Elektronik)

Hi, It?s the first time that I design a flyback converter. I want to ask a stupid question. 136173 Is the value of 15V@20mA/15V@3A Absolute Maximum Rating??? If it is "Absolute Maximum Rating",then the transformer can't operate normally when Vin>90v EX: Vin(1-4)=400V (1-4):(5-6)=6:1 Vaux(5-6)=66.67V > 15V So, I

## Transformer matching network design

Dear all, I am a beginner. I need some opinion/help. Here is my situation. I am designing a transformer matching network (TMN) for a PA. I do not have ADS PDK but working in CADENCE PDK. My question is do I have to design layout in CADENCE then export gds file to E.M software such as HFSS/ADS momentum for electromagnetic simulation and

## PA transformer center tap supply (on chip)

Hi all I want to design a on chip transformer with center tap to for PA input and output match and center tap used for bias supply . But the ADS mom designed transformer (SP_black block)used for bias supply in cadence simulation ,My main power amplifier device was not operating in the right quiescent point. Please (...)

## Three winding transformer with symmetrical resonant tanks for isolated dc-dc converter

I am trying to derive the gain |Vout/Vin| vs frequency of a dc-dc converter with isolation provided by a three winding transformer. The circuit includes three symmetrical series resonant tanks (same resonant freq.) for each port. If we simplify the system as shown in the figure attached, which approach would you follow to calculate the transfer fun

## [CST-EMS] Coil design using copper wires

Dear All, I need to simulate a transformer using CST EMS to eddy-current and thermal loss estimation, quite similar to the following application: I designed the transformer coil with copper wire and set simulation to run (I didn't use the coil definition fro

## -ve square wave using a dc voltage

sure, use a transformer with the output center tapped. connect 40V to center tap, and put 5V square wave on primary

## smps problem, simulation vs practice, need advice

i have a SMPS power supply, very similar to the one found at page 30 on this document: my goals are to obtain: flyback configuration Vin=9V Vout=180V Iout=3mA Here is my circuit 126364 - I added primary and seconda

## LTspice smps diode simulation problems

It is called ideal vs real components. Ideal components provide ideal results while real components introduce all the unwanted inductances and capacitances that cause problems and losses. It will get even worse if you model the transformer with a coupling coefficient less than one to include real leakage inductance.

## Questions about RCC switch mode power supply ? Circuit by Andy

This appears to be a blocking oscillator. The principle of operation is not readily obvious. Current increases through the transformer, until it reaches saturation. As flux stops changing, induced current drops suddenly. This turns off the transistor. The process repeats. With the right half of the circuit, it acts as a flyback converter. A sim

## wireless power transfer simulation

I'm not working with Proteus, but I believe it's transformer model can be setup with SPICE inductance and coupling parameters, otherwise consult the documentation. For the inductance of typical coil configurations you can refer to tools on amateur radio web sited like

## determining smps transformer type and primary turns.

Hi folks , please help me understand what kind of transformer i got and how many primary turns it needs, I was driving the transformer but after a while it gets hot and it should let more power through. I will post what I have, the schematic of the smps im using the transformer in and the photos of the transformer itself , (...)

## how to get a high voltage waveform in a cro? what would be the waveforms in this?

You will need an isolation transformer and a high-voltage probe for your scope. simulation results show to expect quite high voltages.

## Flyback supply, translating from LTSPICE to pcb design.

As a first point, you should consider the datasheet. Bias input shouldn't be supplied with > 15V in normal operation. I presume that at least the RCD snubber has to be adapted to the actual flyback transformer parameters, particularly leakage inductance. The simulation is for 5V output, but you are attempting 25V?

## how to Define the transformer Primary & Secondary windings in SIMetrix ?

Hello, I am using the center-tapped transformer in SIMetrix simulation tool. The exciting tuns ratio of the transformer are 8:2. The primary tuns I have set to 8 turns according to the ratio. Now, what value I have to give to the Ratio to primary 1 ? (See in the attachment) Is the value of 250m or 2 according to ratio?

## Flyback LED driver with unusual error amplifer connection is poor?

There is nothing wrong with using Bottom rail for CM & DM reference; that is what it is designed to work with on this chip, but there may be CMRR penalties for noise below ground. The use of ground on both sides of transformer and then use an optoisolator is wrong. The bigger problem could be your lack of requirement specs for all PSU designs.

## Analysis of H-Bridge Circuit

Looking at your schematic... Running a simulation... One end of the secondary is connected to the node between IGBT's. It only conducts when either left-hand IGBT is switched on. This technique allows the capacitors to send juice to the transformer, in the reverse direction. Is this the method that lets you charge the battery? Looks clever. The

## Transformer to the Power Supply

Hello, I have just found a voltage regulator, LM2735, which could be a possible solution to my power supply (see the picture). But I am having hard time finding a proper transformer to the power supply. My output voltage should be ?10VDC. The input voltage is +5VDC. A transformer with a turn ratio of 1:5:5 should be good for this purpose, I

## how to improve the L, Q and the efficiency?

I have simulated a transformer proposed in the following paper, but I got very low L, Q and efficiency. Can you tell me what's wrong with my workspace, mml_wrk.zip, in ADS2011?
