On July 30th I posted the schematic of a 3000W modified sine-wave inverter. It has many parts but a sine-wave inverter that uses PWM is much more complicated.ebuka_2 said:Are you are talking of the first or the second? B'cos I can remember that one of them is complicated.
audioguru said:Yes of course there are better transistors than the old 2N3055.
But this simple and cheap square-wave inverter is used in The Philippines where the 2N3055 is available and better transistors are not.
Mosfets would be much better than transistiors in an inverter.
audioguru said:Are you going to design an inverter circuit that uses African transistors?
