i need to utilize sine wave inverter, here i go with 50Hz/ Vp=4V sine wave and 500Hz/ Vp=5V triangle wave and it gave to 741 to generate PWM signal. out put is Capture1.PNG
when i going to increase triangle wave frequency to 1KHz it out put is Capture2.PNG
i think 1KHz signal is not making required PWM Pulses and need to clarify 500Hz triangle wave ,is it enough to this type of designs.
Furthermore, I add a H-Bridge and a transformer (pri 100mH, sec 10mH,) as following Capture4.PNG
and its out put is Capture3.PNG
i need to Utilize 230V,50Hz ,5A max sine wave inverter, Am I missing some steps to do this?
