A novel wavelet modulation scheme for single phase inverter

DC-AC Inverters are key components in various industrial applications that include power supplies, motor drive systems and power systems. Now-a-days dc-ac inverters (both 1-phase & 3-phase) are finding more attention in renewable energy systems also. In this paper a new kind of switching scheme is discussed where gate pulses for switching of Single Phase 4 pulse voltage source (VS) DC-AC inverters are generated using wavelet modulation. Simulation for different loading conditions is performed and results are compared with results of PWM and Square pulse switching under same loading conditions. The wavelet modulation technique has shown tremendous advantages over PWM technique.
