hi,
i would like to make a dc dc boost converter.The input given is 12V-20V and expected output is 230 V.Can u help me out. This boost is made as part of the inverter. Actually the inverter output is 230V ac. And the power of inverter should be 1KW. I did go through some web pages but stil hv nt got a clear picture. Plz help me out.
Thank you
Merley

I'll give you an idea and hopefully it will help you out if you do a little thinking on your own to fill in the gaps I leave out. Then you can take your idea to your so called "guide" and prove them wrong because this idea does not involve magnetics, however magnetic fields will be a byproduct since a constant electric current produces a constant EM field and changing EM field produces EM 'wave' distortions in the space that travel at the speed of light in a vacuum.
The idea involves the use of switching capacitors in a way to produce a higher voltage. The topology is what you must figure out. I hope this document will enlighten you. Good luck!

Well of course you don't need a transformer, you could probably make a full inverter without any kind of magnetically operated component in it, that includes inductors, transformers and relays. You just need to be creative and think outside the box. I can't agree with what your guide told you. |

hey, i do hv an inverter circuit which is a buck-boost inverter circuit, wher in the switches are operated by hysteresis control method,its a transformerless design.. i am doing this as a project, but my guide says its nt possible to make an inverter without transformer.but i cant find an answer to this. |

If you are interested in teaching yourself about these things then I can see why you want to make one of them. There is such a wealth of information out there now about SMPS and power inverters that it would be much more worth your time to go and study that instead of asking people here to spoon-feed you the information you need to create such a device. If however you had specific problem and have actually showed some effort, then people would be more willing to help you. It's amazing how many people don't realize this. Only trying to help. Follow these rules and you will learn quicker - take the information that is already out there waiting for you to collect. |
