Abstract
Two simple control strategies for current-controlled VSI-PWM (voltage-source-inverter-pulse-width-modulated) transistor inverters are presented. Both methods are based on three-level hysteresis comparators that select appropriate inverter output voltage vectors using a switching EPROM table. The first controller works with current components represented in a stationary coordinate system (AC components) and the second with components represented in a rotated (field-oriented) coordinate system (DC components). The theoretical principles of these methods are discussed. The results of a comparative study are presented which illustrate the performance of the proposed controllers in comparison to the most popular scheme, based on three independent two-level hysteresis comparators.<>Keywords
