This paper presents design and practical implementation of single-phase inverter based on Selective Harmonic Elimination-Pulse Width Modulation (SHE-PWM) technique. Microcontroller Mega type Arduino used as a controller for producing the gate pulses. The optimized switching angles determination results in wide range of output voltage. Depending on number of switching angles, the Lower Order Harmonics (LOHs) can be eliminated to improve the output voltage waveform. A comparison study using Matlab/Simulink for sinusoidal-PWM and SHE-PWM techniques, which shows for the same LOH in the output voltage waveform, the SHE-PWM has less number of pulses per half cycle than sinusoidal-PWM strategy. The reduction in number of pulses results less switching losses. The simulation done using ten switching angles to drive R-L load. A prototype of SHE-PWM inverter with R-L load is used to validate the simulation results

Space Vector PWM (SVPWM) generates less harmonic distortion in the output voltage or currents, provides more efficient use of supply voltage and better voltage utilization compared with sine PWM. In this work, a detailed Simulink implementation for SVPWM for the open loop control of PMSM is presented. Results show the output of the blocks that assembles SVPWM besides the PMSM voltages and currents when exposing the motor to different load torques. The technique of SVPWM enables the load to respond to the change in external load torque. This technique also results in lower total harmonic distortion and better utilization of the dc supply compared with traditional sinusoidal pulse width modulation SPWM
