摘要

在电池供电脉宽调制逆变器中，直流链路电容代表功率密度方面的限制因素。直流电容的大小很大程度上取决于它的电流和电压纹波。本文研究了针对电池供电脉宽调制两电平三相电压源源逆变器直流链路电流和电压纹波的“广义间断脉宽调制”调制方法。“广义间断脉宽调制”已被证明是降低逆变器开关损耗的有效方法。本文进行的参数研究表明，与广泛使用的调制方法“中心空间矢量调制”相比，该调制方法还可以减少直流链路电压纹波。

Influence of Generalized Discontinuous Pulse Width Modulation (GDPWM) on the DC-link Current and Voltage Ripple in Battery-fed PWM Inverter Systems

In battery-fed pulse width modulated inverters, the DC-link capacitor represents a limiting factor in terms of power density. The size of the DC-link capacitor strongly depends on its current and voltage ripple. This paper investigates the modulation method “Generalized Discontinuous Pulse Width Modulation” regarding DC-link current and voltage ripple in battery-fed pulse width modulated two-level three-phase voltage source-source inverters. “Generalized Discontinuous Pulse Width Modulation” already proved to be effective in reducing the inverter switching losses. Parameter studies performed in this paper reveal that this modulation method also enables a reduction of the DC-link voltage ripple in comparison to the widely used modulation method “centered space vector modulation”.
