I was making inverter with one transistor or we call it Blocking oscillator, rating frequency 15 khz This technology used since 80's in automatic power supplies in TVs,but this type of inverters can't be used for the appliances which work on 50 Hertz,so we were making the UPS 50 Hertz inverters with low noise and sign wave while most of high frequency inverters using triangle or square waves.
Hello. I have to admit that you have weirdly wound this transformer and because the gear of this transformer you created is about 1: 30,8. By supplying the lowest voltage of 12 V, and this is keyed by mosfet transistors, the output will have a voltage of 30.8 times that is 370V. You could give more wires side by side to the primary, thus reducing their number from 12, for example to 6, and secondary ones to give one more wire next to each other, reducing your number by half or 185, the transmission would be kept current so that it could increase, then you can check at what frequency SG3525 works to increase this frequency, if any, due to the fact that you are lowering the number of turns, although this would not necessarily be necessary. It is known that the output without load will be also 370V, and with a light bulb load it is only about 230V. For a light bulb it is not a problem because it is completely resistive. In case it breaks when overvoltage and nothing happens. What happens when you connect a TV to it or a laptop power supply, of course, not an inductive one without a 50 Hz transformer. or any drill because such devices on this inverter will not work but they can damage it or damage it. There may be damage to the adapter from the laptop or adapter from the TV due to too high input voltage that can break through the rectifier bridge at the input or some capacitors or something similar. Greetings.
I make this inverter.But it not chopper transformer output voltage correct.output voltage low.output voltage 20 vole.please this chopper transformer correct making?
