“…Modern digital controller technology allows the possibility of implementing more advanced control laws that would be considered impractical with standard analog circuits [13], [26]. Further advantages are the programmability and the reduced sensitivity to external influences as well as simpler implementation and prototyping.…”

Abstract-An efficient high-speed bi-directional data transmission scheme for isolated AC-DC and DC-DC switched mode power converters is presented. The bi-directional scheme supports fast, efficient and reliable transmission of digitally encoded data across the isolation barrier and enables primary side control, allowing effective start-up and a simple interface to system controllers. Another key feature is that the bi-directional communication is independent of coupler gain and degradation and only the minimum number of couplers is required. The digital interface can also be used to transmit auxiliary signals between both sides. For test purposes, the scheme has been implemented on FPGAs and verified using a custom-built SMPC board.

Abstract-Recently, the performance of the DSP and FPGA is developed remarkably. So, fully digital control is enabled in switch mode power supplies. However, in many cases, the control system is built by very complicatedly and very difficult theories such as the adaptive control, predictive control, and so on. Furthermore, in most popular PID control, its design method of the parameters is not clear, so derivation of the optimal parameters is very difficult. This paper proposes revolutionary control technique which is cancelled the transfer function of the converter completely by using pole-zero-cancellation method. This technique is very simple and easy to stability design.
