FPGA-based sliding mode direct power control of three-phase PWM boost rectifier

This paper presents a Field Programmable Gate Array (FPGA) implementation of a Direct Power Control (DPC) of three-phase Pulse Width Modulation (PWM) boost rectifier. The DPC control was synthesized via the sliding mode theory. The main interest of using such theory is the robustness of the resulting control to parameters variations and external disturbances. In the other hand, thanks to the possibility offered by FPGAs to design efficient dedicated architectures, a very important reduction of execution time is performed and only few microseconds are needed for the execution time. Experimental results carried on a FPGA based prototyping platform are given in order to illustrate the effectiveness of the implemented sliding mode DPC of three-phase PWM boost rectifier.
