Abstract:

This system is used to generate the optimal pulse width modulated (PWM) signal for single phase inverter using MATLAB. PWM signals are generally used in motor control application, power electronics and solid-state electric energy conversion. In this system, I am going to generate the optimal PWM with help of MATLAB which reduces the total harmonic distortion. This system uses two PWM patterns, three pulses PWM and five pulses PWM pattern. For obtaining the optimal PWM different conditions are undertaken, case 1 is middle pulse having constant center time & constant pulse width, side pulses having constant pulse Width changing center of side pulses. Case 2 is having [Wm (width of middle pulse) +Ws (width of side pulses)] width constant, center of all pulses also constant, but changing width of middle pulse and side pulse in proportion such a way that [Ws(side pulses) + (a/2)], [Wm (middle)-(a)] where 'a' is constant. That generated MATLAB code gives switching times of optimal PWM waveform. For testing the THD practically FPGA board with inverter circuitry is used. PWM signals are generated on FPGA board using switching times of optimal PWM waveform. That signal is applied to inverter circuit which work efficiently with lowest THD.
