FPGA-Based 2D Addressing Mode in Programmed Matrix PWM for Multilevel Inverter Control

摘要

W artykule zaproponowano programowalny macierzowy przekształtnik PWM bazujący na dwuwymiarowym adresowaniu pamięci FPGA. Otrzymano wbudowany moduł PWM znacznie prostszy od typowych rozwiazań.%Conventionally, control signals fed to the PWM inverters are produced by electronic hardware or microprocessor. The cost and complexity of hardware implementation are considerable and control algorithms differ for PWM for different levels and topologies is proposed. On-line computation in the microprocessor approach is laborious and time-consuming. These two approaches seem impractical when they are applied to PWM multilevel inverter control. In this paper, programmed matrix PWM based on two dimensional addressing modes for FPGA memories can solve the problems mentioned above and provides easy, fast and steady control. Experimental results are carried out to confirm the high performance of the proposed embedded PWM.
