    Advice for a Power Supply Layout

    Hello everybody!! I designed a power supply for running a magnetron. Thus in the output stage I must have 4.3 k and the output power will be around 1.2 kW. I would like to hear your comments/advices/recommendations for my layout. Thank you for your help Schematic (pdf): Images...

    Transformer modeling and measurement

    Hi everybody!! I have a transformer from a LLC PSU, that I need to get its model, in order to be able to simulate it. The transformer looks like the following: It is center tapped to VCC, W1 and W2 has 5 turns. The only winding that could affect the resonant frequency, I think, is W3, that...

    How to start an embedded project?

    Hi everyone! I am starting a new project, that finally it will be embedded. I think I'm going to do it in LabView and use it in a compact Pc with Windows CE 6.0. The problem is at the moment I don't know exactly how much peripherals will I need and I don't know how much computing power will I...

    Key Concepts developing a test bench bed for an inverter connected to the public grid

    So finally it should be something like this: Hardware Check the correct sensing of the voltage and current of the different inverters and plugs Check the isolation of the sensing lines. Check the protection against overcurrent and overvoltage Check its immunity to EMC, both conducted and...

    Key Concepts developing a test bench bed for an inverter connected to the public grid

    So I have to add "Check the HEMS front overcurrent and overvoltage" in Hardware testing. What do you mean with just one synchronising circuit? Thanks Regards

    Key Concepts developing a test bench bed for an inverter connected to the public grid

    Hey there! I need to write a short document about how I should approach the develop of a test bench for the control of various inverters conected to the public grid. I attached a picture of something looking like I mean. It should be like HEMS in the picture. Firstly I thought in these...

    Ideas for new project

    Hi everyone; I am Sergio Toledano, from Spain. In my student years I used to study power electronics, but now I work in a company developing sensors.There I realize the importance of programing languages. I want to start a project in my house as a hobbie, which mix power electronics and digital...

    Looking for a silicone membrane switch

    Hi everyone! I'm doing a new product and now I have to seal it. It will be in plastic ABS, the problem it's that I want to get the ip67 grade at my product but I have a tactil switch in the outside. So I need a cap to seal it like this: The problem it's that I don't find any standard product...

    Ideas to obtain 12VDc from 400VAc

    Finally today I tried to put the Myrra 47134 in series to handle this increased tension and they work properly. So I think I will continue with this idea, proving that it doesn't heat when it works for so long. thanks you very much.:grin:

    Ideas to obtain 12VDc from 400VAc

    Thank you both I've been thinking about the design all day and I think I should focus more on solving the problem as genovator says. As for the specific application it's for use in industry and it will be part of a sensing system. It Will be a series of five prototypes and if the result is...

    Ideas to obtain 12VDc from 400VAc

    Hi everyone! I want to desing a power supply to obtain an output of 12V from an input in the range of 85V-400V AC or DC.It has to supply 3W. I've thought to use electronic transformers, (myrra 47134) that some of its advantages are high performance, wide range of input voltages and operating...
