An Optimized Multilevel Inverter for 3 Phase Induction Motor Drive Using Switched Capacitor
نویسندگان
چکیده
An optimized multilevel inverter is implemented for 3 phase induction motor drive. The Main Feature Of this Circuit is to boost of the Battery Voltage as twice as possible along with multilevel staircase output voltage which approaches nearly sinusoidal wave. By using appropriate switching strategy of two capacitors the desired waveform can be achieved, hence significantly reducing the number of capacitors for a given number of levels. Based on using only two capacitors, a 13-level inverter is analyzed. Total harmonic distortion is obtained by Fourier analysis. Hence the results are given to confirm the theoretical analysis.
