摘要

本文讨论了空间矢量脉宽调制在DC-AC变换器中的应用。这里使用的转换器只不过是一个三相逆变器。产生6个脉冲，用于触发逆变器中使用的开关装置。逆变器根据这些脉冲在负载端输出三相电压。星形连接的电阻和电容负载在逆变器输出中使用。两个正弦信号被用作该svpwm单元的输入。Svpwm技术是脉冲产生的最新发展趋势之一。与传统的pwm和正弦pwm相比，这种svpwm产生三相逆变器所需的精确脉冲。该svpwm基于扇区形成产生脉冲。该逆变器的输出电压由总谐波失真的减小值构成。

Space vector pulse width modulation for DC-AC converter

This paper deals about the concept of space vector pulse width modulation for DC-AC converter. Converter used here is nothing but a three phase inverter. Six pulses are generated for triggering switching devices used in the inverter. Based on these pulses inverter is delivering its three phase output voltage in the load terminals. Star connected resistive and capacitive load is used here in the inverter output. Two sinusoidal signals are used as input for this svpwm unit. Svpwm technique is one of the most recent trends in the pulse generation. Compared to conventional pwm and sinusoidal pwm this svpwm generates the precise pulses which is required for the three phase inverters. This svpwm generates the pulses based on the sector formation. Moreover output voltage of this inverter is formed with the reduced value total harmonic distortion.
