Abstract: This paper presents general study of Pulse Width Modulation technique, and Summarizes common PWM Inverters for its large practical importance in power electronic systems (PWM is the basic control technique in power electronics). This paper investigates AC induction motor shaft voltage problems, current flow through motor bearings and electric discharge current problems within bearings when operated under both pure sinewave and pulse width modulated (PWM) inverter sources. Experience suggests that PWM voltage sources with steep wavefronts especially increase the magnitude of the above electrical problems, leading to The nine-level multi-level inverter (MLI) uses a DC voltage supply, seven switches, four capacitors, and twelve diodes to generate an AC output with nine distinct voltage levels. Our proposed scheme has been designed in MATLAB/SIMULINK environment showing performance measures. A zero voltage switching (ZVS) pulse-width modulation (PWM) inverter that uses a parallel-resonant DC link (PRDCL) circuit is examined. The output efficiency with calculated parameters is being monitored as the circuit performs on the hardware kit. With PWM, the input voltage of the inverter can be chopped into discrete pieces, and thus form a desired output signal. The PWM switching frequency can vary greatly depending on load and application. Additionally, a comparative analysis with conventional two-level inverter technology is provided, highlighting key differences and demonstrating the potential advantages of adopting multilevel inverters. The best voltage signal for these purposes is one with a periodic time variation in which amplitudes of selected non-fundamental components of the Hysteresis controller is used for Current source inverter and all the remaining PWM techniques are used for Voltage source inverter. PWM is commonly used in applications like motor speed control, converters audio amplifiers etc. The ever-increasing reliance on electronic devices which utilize AC power highlights the problems associated with the unexpected loss of power from the electrical grid. There are several different PWM techniques, differing in their methods of implementation. After filtering, the output voltage is different from the voltage at the output of the converter because the LC filter is a second-order element of the form. The power converter, which is an inverter in this case, is driven by a gate driver. PWM techniques achieve efficiencies up to 90% while minimizing output current distortion and power dissipation. Control strategies include Volts per Hertz, Sensorless Vector Control, and Field Oriented Control. The best voltage signal for these purposes is one with a periodic time variation in which amplitudes of selected non-fundamental components of the 4.
