Abstract

The use of pulse width modulation (PWM) in inverter’s applications has become popular over the years. This is because it has a well-designed control strategy which allows control of the output in noiseless and more efficient ways. However, inverter’s design often requires the analysis of the main components involved. This paper presents a design analysis of a 0.5hp three-phase induction motor driven by a pulse width modulated (PWM) inverter. The mathematical models for the circuit elements involved are derived analytically. The derivation of line current, circuit elements, switching frequency, harmonic voltage, pulse width and its location for a three-phase modulated inverter were presented using Fourier series analysis. The numerical values for the 0.5hp induction motor obtained are 370Ω, 680mH and 3000Hz for resistance, inductance and switching frequency respectively. The design approach can be employed in other applications.
