摘要

本文提出的基于模拟量的改进直流-交流逆变器PWM控制方案可以消除直流电压源不恒定引起的低次谐波分量。采用一种简单的高功率因数全桥整流器和充谷滤波器来实现非恒定直流电压源。本文介绍了一种用于PWM控制的修正三角信号的研制。计算机仿真和实验结果验证了所提出的改进PWM控制方案的性能。

PWM control using a modified triangular signal

The proposed analog-based modified PWM control scheme for the DC-AC inverter can eliminate the low order harmonic components caused by the nonconstant DC voltage source. A simple high-power factor full-bridge rectifier with the valley-fill filter is selected to realize the nonconstant DC voltage source. The development of a modified triangular signal for the PWM control is introduced in this paper. The performance of the proposed modified PWM control scheme is verified by using computer simulation and experimental results.
