hello everyone.
its a simple in-efficient inverter with the basics config (roughly over 150W)...
it works, but my problem is cross over distortion.
when i try to put loads such as energy saver bulbs, they flicker. although resistive loads are ok.
Audio Guru posted a circuit with diodes in place at the setting transistors.
i used different transistors, darlington TIP122. since i need roughly 2amp to drive the power transistors, i voltage divider biased my setting transistors...
so where am i suppose to insert diodes to overcome distortion, so that both pair of transistor are just on for a fraction of a second..
here is rough sketch... (dont mind the drawing, i'll make on in some circuit program and post it again)
thanks in advance to those who help..
