Abstract :
In this paper, we propose a novel scheme to generate sinusoidal pulse width modulated (SPWM) switching pulses using Direct Modulation Strategy and its implementation has been done through software developed using VHDL code. In the given proposed scheme, the periodic PWM signals are generated, separated by positive and negative group of polarity control switching pulse and evoked at the output as a control signal for FPGA interfaced H bridge inverter circuit.
