| Abstract | ||
| This paper represents new method to determine the optimum switching angles for Selective Harmonic Eliminated PWM (SHEPWM) inverter. Such switching angles are defined by a set of nonlinear equations to be solved using the Resultant method. This is done by first converting these equations that specify the harmonic elimination problem into an equivalent set of polynomial equations. Then, using the mathematical theory of Resultants, all solutions to this equivalent problem can be found without the need for any initial guess. The complete solutions for unipolar SHEPWM switching pattern which produce the fundamental while not generating specifically chosen harmonics are investigated. | ||
