Hi Phrak,
thank you for your interest. Could you please give more detailed info about your calculation. Because i found the correct inductor value just by playing with the values of it and checking the sinus waveform and measuring the temp. Actually our output is 220Vac-50Hz but i think the...
thanks, actually studied on 110w inverter but the power components we used is for 1kva so you can load it to 1kVA. This inverter is DSPic controlled so just need to change its controlling parameters. Next stage of this product will be 12-24-48 or 110VDC input and 220Vac output.
I am using two IGBT's one for neutral and one for phase.
Also i found the right choke for the system. 12mH E type choke with 3uF capacitor i get clean sinus waveform. And the temp. of the choke does not rise.
Actually, i do not have so much knowledge about the Cycloconverter but i know this system is mainly use in controlling speed of AC motor. Also it is not easy to find into the market.
The system i described above is more common one.
It is not so easy to convert 50Hz to 60Hz,
First of all you need to convert your incoming AC to DC and then by using IGBT modules (Driving them by PWM modulation) invert the DC to AC again. This is UPS topology and for frequency converter the topology is same. you only need to play with the...
Hi all,
i am working on an 110W inverter (Dc to AC) project that the input voltages varies from 700Vdc-1000Vdc and the output voltage is 220Vac.
The system operates, however i have problem with output choke. The output choke temperature increases instantly even in no load operation. My...
