摘要：

This paper presents a technique for reconstructing converter line currents using the information from a single current sensor in the de link of a converter and comparative evaluation of the performance of single sensor control techniques in the de link for voltage-source pulsewidth modulation (V-S PWM) converters. When 3empty set input currents cannot be reconstructed, three methods to acquire the de-link current are compared. Two of them are methods of modifying the switching state (I, II), and another is a method of using the predictive state observer. Also, compensation of sampling delay, and a simultaneous sample value of input currents in the center of a switching period are included, Suitable criteria for the comparison are identified, and the differences in the performance of these methods are investigated through experimental results for a typical V-S PWM converter rated at 10 kVA.
