DEVELOPMENT OF INDUSTRIAL DIGITAL INVERTER AND ITS APPLICATIONS Ba Da Park Dept, of Interdisciplinary Program of Mechatronics Eng., College of Eng. Pukyong National University

In this thesis, the development results of digital inverter (DI) and its applications are introduced. A simple PI controller is proposed to make the output current track the constant setting current. Based on microprocessor (PIC16F73),  the  control  system is  designed  and  developed.  The  developed  digital  inverter is  applied to  welding machine and Brown gas generator.
