| Abstract |
In the paper two simple control strategies for current regulated VSI-PWM transistor inverters are presented. Both methods are based on space vector approach. As regulators three-level comparators are used. The outputs of the comparators select appropriate inverter output voltage vectors via switching table stored in EPROM. The first regulator works with current components represented in rotated (field oriented) coordinate system (dc-components) and the second one with components represented in a stationary coordinate system (ac-components). The theoretical principle of these regulators are discussed. The simulation and experimental results of comparative study which illustrate performance of the proposed regulators in comparison to the most popular scheme based on two-level histeresis comparators are presented. |
