Report inverter in Power Electronics Posted March 14, 2011 @Hero999,Thanks for the comment. You are right and i was not wrong as well. I only need to make myself clearer: there are two duty cycles in a complete cycle one in each half(+ve & -ve) and each makes 25% of a complete cycle.Switched mode inverter? yeah, i am aware of its advantages. i have not tried it out as i have not been able to get transistor that can handle that voltage in our local market.
