摘要

本文介绍了在基于现场可编程门阵列(FPGA)的逆变器中实现的电流控制环的精度和带宽的提高。通过前馈控制补偿IGBT功率级的非线性效应，减轻了电流控制器的负担，从而使输出电流谐波更少，频率响应更好。为了进一步改善电流控制回路，在Luenberger观测器的基础上实现了电流观测器。

Improved high bandwidth current controller for FPGA based inverter drives

This paper presents the improvement of the precision and bandwidth of the current control loop implemented in a field programmable gate array (FPGA) based inverter. By compensating the nonlinear effects of the IGBT power stage with a feed forward control, the current controller is relieved resulting in an output current with less harmonics and a better frequency response. In order to improve the current control loop even further, a current observer, based on a Luenberger observer is implemented.
