Design of a fully digital controller for a shunt three-phase active filter using VHDL-AMS language

“…They allow effectively designing of a fully digital control. Specifically, the method proposed in [9] simulates the converter power stage using Virtual Test Bed and controls it using the actual converter digital controller, with an FPGA control system interfaced through the PCI bus of the host computer. However, these tools generate automatically the VHDL code and thus no architecture optimization is possible [9,10].…”

“…Specifically, the method proposed in [9] simulates the converter power stage using Virtual Test Bed and controls it using the actual converter digital controller, with an FPGA control system interfaced through the PCI bus of the host computer. However, these tools generate automatically the VHDL code and thus no architecture optimization is possible [9,10]. In our approach, by using existing methodology [13], we developed an improved VHDL-AMS-based design flow for an optimised digital control design of a power electronics application.…”

“…The "architecture 1" is naturally imposed by the equations (1) to (9). The data flow graph (DFG) of this architecture is presented in Figure 9.…”

“…As far as Power Electronic applications are concerned, similar design approaches for fully digital control could be considered [7,8,9,10]. High-level analysis of a multidisciplinary system, functional validation at any design step, top-down design approach, simulation at various levels of abstraction and final physical design are the necessary tasks that need to be carried out to design well and optimise the digital controller till its final physical implementation.…”
