FPGA Based Implementation of Amplitude Modulated Triangular Carrier PWM

摘要

Metoda modulacji amplitudowej fali nośnej trójkątnej AMTCPWM umożliwia rozszerzenie możliwości klasycznej metody sinusoidalnej PWM SPWM. W pracy zaprezentowano wykorzystanie układów FPGA.%The amplitude modulated triangular carrier pulse width modulation method (AMTCPWM) is a natural sampled PWM method which can extend the linearity of the sinusoidal PWM (SPWM) to full range of the pulse dropping region and increase the dynamic range of the SPWM control. Any submission in the PWM theory with a specific performance target is mandatorily requires either a reference or a carrier modification. This paper presents a reprogrammable architecture to implement the AMTCPWM with perfect reproduction capability. The architecture is implemented using Spartan 6 family device LX45 using Modelsim 6.3 and Xilinx 13.2i.
