The pin 10 of the 3525 is power down and the only thing in that schematic that is connected to that pin is a resistor from pin 15 witch is Vref 5.1V. Yhe idea is that vhen the switch from pin 10 grounds the chip he turns on. When the switch is turned of and the Vref is on pin 10 3525 is in it's...
I have build a coil on a CM270060 core. It has almost 3mh.
Now I have a beautiful sine output and the core doesn't get warm. I have tested the inverter with 1x21w light bulb, 2x21w light bulb and 2x21w lightbulb and laptop.
The maximum output power I tested was 90w. In this time the...
Hello to all.
I have built a pure sine wave inverter from 12v to 230v AC at aproximately 500W.
The DC/DC converter is the usual forward converter with sg3525 and ETD39.
Now my actual problem is the LC filter at the output.
The output is 50HZ sinewave.
The SPWM is 24.3KHZ.
The H bridge...
how about installing ip webcam on the phone and using an universal MJPEG video streaming driver?
I tried using thise combination on my windowsphone and it works greatly. Windows 7 on the laptop sees the phone as a usual usb conected webcam. I tried it on yahoo messenger only but in theory...
Hello to all.
I am building a 1000w pure sine wave inverter.
It has a 12V to 320V converter made with an SG3525 controller and BD139/BD140 at the output as a driver, 2 ETD39 ferrite core, each of them driven by 4 IRF3205 fets.
The secundary winding of the transformers is in series ( they are...
