Minimization of harmonic distortions in voltage source inverters' output wave form is very important. In this paper, a single phase inverter design that can change the operating frequency between 5 Hz 50 Hz to achieve the keeping the voltage/frequency ratio (V/f) as constant during single phase asynchronous motor driving is presented. For the aim of minimizing the voltage harmonics, pulse width modulation (PWM) based selective harmonic elimination method (SHEM) is used in the design. Via this method, 3., 5., 7., 9., 11. ve 13. harmonic components of the inverter output voltage are eliminated while regulating the amplitude of the main harmonic component. A practical application circuit is installed for the proposed design. The obtained results have shown that the proposed design is efficient in reducing of harmonic distortions
