Abstract
Active converter has some advantages such as controllable DC bus voltage, bi-directional power flow and unit power factor which can provide the current,almost like sine wave, to the AC grid. These above advantages can help converter to achieve the industrial standard. However, due to the nowadays progress of power electronic and digital control, the instrument and programing language are becoming more and more complex. It takes a long time for the designer and user to operate these complex instruments even to understand and redesign the program.This thesis proposes that using LabVIEW software to design and program a user interface which can implement to the active converter. Because of the friendly design interface, user can quickly operate the instrument and easy adjust the system parameters to increase the efficiency and quality for designing process.
