A modified sine wave inverter is designed by utilizing a PIC microcontroller and a push-pull topology. The push-pull configuration operates MOSFETs as switches and a control circuit controls them to produce a stepped-up battery voltage with a modified sine wave form. The control signal is generated by the PIC16F87A microcontroller. At the end of this … Read more
