Still unable to make the same thing that you had made.:sad:
Source settings (from top)are -
1. Max voltage=5, sawtooth, f=1kHz, offset=5v
2. Max voltage=6, A/C, f=50Hz, offset=0
3. Max voltage=5,sawtooth, f=1kHz, offset=5v
4. Max voltage=6, A/C,f=50Hz, offset=0
@BradtheRad: Thanks for your valuable feedback.I tried to make circuit in Circuit Simulator v1.6i to check the waveform as you gave in the above post but didn't find the Triangular wave generator.
It would be great if you could help in this regard.
After some modification and tests, I've got the below results -
1. To test my inverter at a low voltage, I made another secondary winding with 16/17 turns which gives 45v dc after rectification and filtration (LC). Then I got the following output -
It seems okay.
2. Then I connect a LC...
I've checked with 12v battery as inverter input; it worked but the output waveform was not as expected. The waveform was 50Hz square (almost) wave. As per my understanding the output should be as like as below figure (as I did not use filter) -
I've checked the waveform at the 6 optocouplers...
All the MOSFETs' Gate and sources are connected to each 18v volt's +ve and -ve terminal. MOSFETs are turning on. I've checked with a separate 12v battery.Battery connected to high side MOSFETs' drain and low side MOSFETs source by disconnecting filtered output of 326v. It gives output. When I...
I've made all there bridge and filter added to them. I checked them separately and found around 18v which is alright to drive MOSFET.
Now, some questions have come to mind regarding the h bridge converter circuit given in post #7.
1. -ve terminal of lowest coil's bridge and the -ve terminal...
I've faced a strange problem. When I measure the secondary coil voltages (3 coils for gate drive) it is showing around 16 peak voltage (and 32 p-p voltage). But when I connect it to Bridge rectifier (4 1N5819 diodes) it shows around 40v dc without the filter circuit. How it could be possible...
Oh!
Actually, I didn't concentrate on those important things (output current capability of Opto and the resistance). I picked up an optocoupler and design the circuit. But now I should consider all those things. Max collector current of 4N35 is 100mA. I think I should consider for more current...
