IMPLEMENTATION OF 3- LEVEL LC SWITCHING BASED NPC-MLI

The three phase LC Switching based voltage boost NPC inverter, to boost the DC input source and also inverting AC voltage in three phase level. The Three level three phase NPC inverter mainly used 12 IGBT switches based on PWM controller systems. The switching pulse gives the sawtooth and pulse generation based pulse to inverter switches. The NPC Quasi Z-Source inverter is the input current is continuous in nature but, it uses equal values of four inductors, four capacitors and two diodes in the intermediate nonlinear converter. The DC input source to inverter using NPC Quasi ZSource with RL series branch and nonlinear converter to DC link capacitor level with connect the load
