Abstract

This paper presents a digital implementation of the modulation technique based on the PD-PWM using a FPGA (Field Programmable Gate Array) with its logical structure developed through the VHDL language. The technique uses a modified modulation and two triangular carriers which it´s applied to a five level hybrid multilevel inverter (based on the Half-Bridge and ANPC topologies). The experimental results validate both the digital development of the technique on FPGA and the presented inverter.
