Abstract |
|
In recent years, industry has begun to demand higher power equipment, which now reaches the megawatt level. Controlled ac drives in the megawatt range are usually connected to the medium-voltage network. Today it is hard to connect a single power semiconductor switch directly to medium voltage grids. For these reasons a new family of multilevel inverters has emerged as the solution for working with higher voltage levels. They can generate output voltages with extremely low distortion and lower dv/dt, they draw input current with very low distortion, they generate smaller common mode voltage and they can operate with a lower switching frequency. Because of these features worldwide research and development of multilevel inverters is occurring. In this report the simulation results and its comparison of diode clamped 3 levels and 5 level inverter has been shown. |
