Abstract |
|
All renewable sources use power electronic devices specially multilevel inverters to convert DC source obtained from renewable sources into AC. These inverters can give their best results when the proper scheme is applied for obtaining desired output. There are many PWM schemes available for inverter operation to obtain variable voltage and frequency supply for inverter. The carrier based sinusoidal and space vector PWM(SVPWM) is the most widely used scheme for the voltage source inverters due to their easier digital realization and better DC link utilization. A simplified algorithm for the three-level SVPWM is proposed. Due to the geometrical symmetry of six sectors, there exist the close relationships in on time calculations and on time arrangement for switches between them. So it can complete the computation of the three-level SVPWM in one sector. |
