摘要

在经典空间矢量法和基于载波的电压源变换器广义间断调制方案的基础上，提出了两种三相电流源变换器广义间断脉宽调制方法。它们在线性和过调制区域都可行，提供了已知的电压源变换器中基于载波的不连续调制的优点——降低了开关损耗和有效开关频率，特别是在过调制区域。在电流源逆变器上实现了这些调制方案，并给出了实验结果来验证概念和理论。

Carrier-based discontinuous PWM modulation for current source converters

Two generalized discontinuous carrier-based pulse-width modulation (GDPWM) methodologies for three-phase current source converters (CSC) are developed based on the classical space vector method and the carrier-based generalized discontinuous modulation scheme for voltage source converters (VSC). With feasible operation in both the linear and overmodulation regions, they provide the known advantages of the discontinuous carrier-based modulation in voltage source converters-reduced switching loss and reduced effective switching frequency especially in the overmodulation region. These modulation schemes are implemented for a current source inverter from which experimental results are presented to verify concepts and theory.
