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.
