Analysis and Modeling of Converter with PWM Output for Two-Phase Motor Applications

P. Zaskalicky, B. Dobrucky, M. Prazenica


This paper presents a steady state analysis of two-phase voltage-source converters with pulse width modulation (PWM) and output voltage control for small two-phase motor drives. The mathematical models of the different converter connections are built on condition of assumption of idealized semiconductor devices. A complex Fourier series approach is used to predict to terminal voltage and current waveforms.
