A Forward Converter Having an FPGA-based PID Controller with Parameters On-ine Tuned

In this paper, a forward converter based on a field programmable gate array (FPGA) technique is presented to design the PID controller as well as to process the signals from peripherals, so as to obtain good performance over the entire operating range. The on-line tuning of controller parameters is used to reduce the effect of input voltage variations on the transient load response. Besides, the improvement in the transient load response is considered further, especially for the maximum voltage input. The validity of the proposed control topology is demonstrated via some experimental results.
