These notes present solutions for the implementation of control software, with practical, imperix-related aspects in mind. They mostly focus on one specific subsystem and may link to other technical notes if needed. Technical notes are application-independent.
This technical note shows how an SPI communication link can be established between an FPGA and an external Analog-to-Digital Converter (ADC). The development setup will…
This technical note presents an FPGA-based Direct Torque Control (DTC) of a PMSM motor using Vivado HLS, coupled with the possibility to customize the FPGA…
This note provides insights into the operating principle of a synchronous reference frame PLL (SRF PLL), also known as DQ-type PLL. An implementation of an…
This note presents an FPGA control implementation of a grid-tied current-controlled inverter. It combines several control modules presented in different Technical Notes to form a…
To implement power converter control algorithms in an FPGA, it is often required to develop an FPGA-based pulse-width modulation (PWM) module. Therefore, this note presents…
This page presents some useful Xilinx IP cores for Vivado. These IPs use the widely used AXI4-Stream protocol to easily exchange data with other Xilinx…
High-level synthesis (HLS) tools greatly facilitate the implementation of complex power electronics controller algorithms in FPGA. Indeed HLS tools allow the user to work at…
The operation of a grid-tied power converter (such as the 3-phases PV inverter) requires that the control software implements a grid synchronization technique. One well-known…
Control algorithms for power electronics converters often rely on PI controllers executed on the CPU of the controller. That’s the technique used in most of…
Introduction This technical note presents the implementation of an interleaved buck converter (multiphase step-down converter) and details an appropriate sampling method of the different currents…
