| Summary: | 碩士 === 國立臺北科技大學 === 電機工程系電力電子產業研發碩士專班 === 103 === The objective of this thesis is to design and implement a three-phase AC/DC converter controlled by modeless predictive current control. The special features of the modeless predictive is to predict the optimal switching states in compliance with the cost function using the sensed current while not requiring the converter model. Only addition and subtraction operations are used, neither multiplication nor division operation is required, the implementation is simplified. Moreover, since converter model is not required in the presented modeless predictive control method, the impact of converter parameter can be significantly reduced.
A prototype is realized with the following specifications: input voltage = 220 V/AC, output voltage = 380 V/DC. And the output power is 1000 W. A DSP, Renesas SH7216 is used as the controller to realize the presented modeless predictive current control in software. Both simulation and experimental results demonstrate that the input harmonics meet the IEC61000-3-2 Class A and output voltage can be well regulated and thereby confirming the effectiveness of the presented control technique and design of three-phase AC/DC converter.
