CONTROL AND DESIGN OF THREE-PHASE 3-LEVEL NPC INVERTER WITH LC FILTER A. Control System A control system of a grid connected three-phase 3-level NPC inverter system as shown in Fig. 3 consists of two main controllers; the DC-side controller for the boost DC/DC converter, and AC-side controller for the inverter.
The filter design is optimized by considering the worst case harmonics which could occur in three phase inverter. This design approach yields compact filter compared to traditional design procedures, which do not account for the cancelations of carrier band harmonics in three phase inverters.
The measured three phase voltages are transformed to the synchronous rotating reference On the other hand, the phase voltage of the 3-level inverter has five levels to the mid-point: Vdc, Vdc/2, 0, -Vdc/2, and –Vdc. The phase voltage depends on the switching frequency fs that is higher than the grid frequency fN.
Primary goal of restricting the aforementioned constraints. The filter design is optimized three phase inverter. This design approach yields compact filter inverters. The trade-off between selection of resonant frequency and harmonic attenuation has also been explained quantitatively. in the event of islanded operation of converter. The proposed
