A Novel approach on ɸ- Disposition Pulse Width Modulation for Modular Multilevel Inverter

In this project implemented a novel approach in the modulation technique based on selective virtual loop mapping, to attain dynamic capacitor voltage balance without any compensated signal.An improvised proposed method, phase disposition pulse width modulation (PDPWM) technique is the main aspect for modulator field in a multilevel inverting model, which also used for Photovoltaic grid connection. Establishing the notion on virtual sub module (VSM), a rapport forming among the real & virtual sub modules.It doesn’t need any sorting voltages, which makes it suitable for a modular multilevel converter with a large number of sub modules in one arm. In which the voltages of the upper / lower arm’s capacitors can be well balanced. This method is more easy when compare to carrier phase – shifted PWM (CPSPWM)and it is to be realized in field-programmable gate array and has much stronge
