Abstract
At present nine-level PWM inverters are introduced in industrial drives, for interconnecting the renewable energy sources into the grid supply and traction motor drives, where the high and medium voltage levels. This paper presents an attempt made to evaluate the performance of 9-level cascaded inverter supplying power to a 1-Ø induction motor using computer simulation. Mathematical modeling of the system derived using equivalent circuit and the device operations. MATLAB/ Simulink based performance study completed. A novel technique used for modulation process to generates the pulses. These are applying to the gate circuit of the solid-state switches are used to configure the nine -level inverter. Simulation study completed using ODE 23 solver and results are presented. Index Terms—PWM inverter, nine -level, 1-Ø induction motor
