A NEW DESIGN METHOD OF OUTPUT FILTER FOR SPACE VECTOR PWM FED INDUCTION MOTOR

Abstract

This paper proposes a new simplified method for design, simulation, implementation, and obtaining optimum value of ac output filter to the SVPWM inverter fed induction motor using the benefit of PSIM program is developed. Also a complex mathematical equations and transfer functions are not desirable. The L-C filter cancels all harmonics and a real pure sinusoidal output voltage and current is obtained. Due to the flexibility of PSIM software, the values of L-C combination are obtained by trial and error method. The advantage of this method, it can vary the values of inductor and capacitor until the value of desired outcome is obtained. Experimental and simulation results have verified the superior performance and the effectiveness in reduction the harmonics of the proposed filter.
