Abstract :
This paper details the design of a digitally controlled isolated SMPC containing a novel bi-directional data transmission scheme The bi-directional data transmission scheme avoids the effects of opto-coupler aging, allows the use of digital control techniques and enables transmission of auxiliary data from primary-to -secondary and secondary-to primary. The complete digital controller was implemented on one custom and two FPGA boards.
