Current Programmed Control of Three Phase PWM AC-AC Converter
A Thesis for the Degree of Master of Engineering Yulong Li
Department of Electrical Engineering Graduate School Yosu National University February 2006
Abstract
In this thesis, a new scheme of current programmed control for three phase PWM AC-AC converter is proposed. Compared to duty-ratio voltage control, current programmed control has several advantages such as reduction of system order, inherent current protection and robust output. By considering only the magnitude components, a similar scheme in the DC-DC converter can be extended to the three phase PWM AC-AC converter. The proposed current programmed control will be well adopted into various converter topologies and three phase PWM AC-AC buck, boost and buck-boost converter are treated. The converter analysis is carried out by applying the vector DQ transformation to obtain physical insight into the converter operation and to establish some important characteristic equations for control purpose. The experiment results show the validity of the proposed scheme.
