In the embedded distribution control system, the analogue quantity under test is usually nonlinear. In order to realize fast and accurate detection of it we present a multipoint calibration, which includes two program editing thoughts: subsection linearization and subsection variable slope.
Current sensing and sharing are important functionalities for paralleled and multiphase power converters. For reliable and efficient operation, current sensing accuracy and the current sharing performance are required. Therefore, sensing errors and mismatches should be eliminated and calibrated. On the other hand, conventional current sharing controllers are designed to force equal current sharing...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
