I am trying to make an inverter circuit that can operate in 50Hz to 50kHz range by using Trimmer (variable resister in the place of Rt and Rt is 1K to 1M Ohms).(Ct=0.01μF)
but the problem I am facing is I am not able to get variable frequency by tuning the trimmer values. I am only able to get 48Hz to 50Hz. I am really need some professional advice here.


Can anyone give me a way to move forward on this project please

 

Chapter 6 (obtained by Google) describes the anomalies with the iC - i suggest you - consult the manufacturer

 

1) What is supplying the + and - AC rectified lines?
2) Do you really have an oscilloscope as the MOSFET bridge load and if so is it in differential mode?
