I need your advice. I want to build a pwm inverter as a project. For long I have been trying to use thyristor as a switch with ICL3038 as waveform generators. I encountered a lot of problems so I was advised to use mosfet, bcos of time factor I yielded. Parts of the problems are:getting the inductor & capacitor optimum values for commutation and how to winding the inductor. I intend using McMurray-Bedford configuration but I was told that with 12-24v dc input and 240voutput will not give desired effect bcos of push-pull effect of tightly coupled inductors. In literatures(Rashidower Electronics & also C Lander)high dc voltage are often used as design example . Many pple here are familiar with mosfet but not so with thyristor.Not only this, the ICl3038 I want to use has the inscripition"Not recomended for new design" in the manufacturer website. Actually, the spwm control circuit I got was designd in 1994. Bcos of these and others, could you please advise me whether to go back or go ahead with mosfet. Better still I will appreciate if I can get as much information on the two so as to decide which to embark upon.
