Meanwhile, TLP350 is available with higher driving current above 2A. However, you circuit need modification. Eg Remove the diode connected to transistor. Take it supply from the tlp250.
Also, use transistors that is of 2A and high frequency ration like 2s2655(npn)
Note, the current output of TLP250 as stated in the datasheet is 0.5A minimum to 1.5A maximum.
if I may ask! why did you use 67nS for the gate charge calculation?
What is the Frequency of your generated PWM or SPWM?
MOSFET is a voltage-driven device, So the magnitude of current you stated above...
Hi,
Change the 1N4007 to UF4007 or FR157.
Finally, i would suggest the remover of additional driver used (tip41 and tip42).
The tlp250 can drive the 3 mosfet.
Can I see your circuit? Tyr and use a simple method. Use an opto coupler circuit to detect the zero crossing and use interrupt on port change input. Use time delay to manage the process.
Try and follow the reference manual from manufacturers of the chip.
For your experiment Reduce the Vs to 15v. Also, for full scale -10v is required at the input and not +10v. Some capacitors value can be change check the datasheet.
Hi,
Visit Microchip website for various bootloader available for series of pic chips. Not all chip can handle the same bootloader, due to internal memory size.
Hi,
why using comparator to detect zero crossing? Is it better than interrupt on input level change.
Meanwhile, using ccp to control the triac you have to know that it is not just to adjust pulse width.
Take Note, zero crossing detection, follow by firing the angle on. The time between zero...
Before the opamp or processing circuit try and create the transformer, since the line frequency is either 50 or 60hz. A transform core of 6,9, 12v at 300- 500ma can be use. Rewind it using transformer ratio formulas to require voltages.
Meanwhile, there many method of processing the output of...
Hi Usama! Please Can you attached the Inverter schematics, because the image you posted is clear. Thanks

Hi Usama! Please Can you post or attached the Inverter schematics with filter you finally implemented, because the Inverter circuit image you posted is not clear. Thanks.
Thanks. I want to make one single board 8 bit based computer for academic use to replace my old 8085 and 68 series from Motorola which I earlier made. Thank for your time.
Is it between one TX and multiple RX or multiple TX and one RX. Which power are you referring to? Rf power?
The datasheet reference manual has the details on how power can be reduce through operation mode.
Since sim card are Programmable card, ask the distributor about the version and features of the sim card you are giving. It can be reprogram by the vendor. Meanwhile, use the sim card that are working. Good luck.
