Abstract

The multilevel inverter fed induction motor drive is simulated and implemented in this research. Multilevel inverters lower the output harmonic content. In a symmetrical circuit, as the number of inverter levels increases, so do the voltage and power. To minimise harmonic distortion, the switching angle of the pulse is chosen. Higher torque and less overall harmonic distortion are two benefits of this drive system. PWM technique is used in the development of the multilayer inverter system model to regulate the induction motor. At these edges, the voltage change rate with respect to time, or dv/dt, is extraordinarily high, ranging from 500 to 5000 V/μs.While three-level inverter topology has drawn interest in high power, high performance voltage drive applications, two-level inverter topology has garnered attention in low power, low voltage drive applications. Low-range power applications are covered by single-phase VSI, whereas medium- to high-power applications are covered by three-phase VSI. The primary goal of these three-level inverter topologies is to supply a three-phase voltage source with constant adjustable amplitude, phase, and frequency. Despite the fact that the majority of applications demand sinusoidal voltage waveforms Key words: multilayer converter topologies, medium-voltage AC drivers
