空间矢量脉宽调制(SV PWM ) 技术不仅具有 线性调制范围宽、输出谐波小和易于数字化实现 的特点, 而且比常规SPWM 高15 的直流电压利 用率[ 1～ 3 ] , 因而被广泛用于变频器、U PS 、无功补 偿器、有源电力滤波器和储能系统电力变换器等 领域. 对SV PWM 常规算法和快速算法进行分析, 并证明了二者的等效性. 同时, 利用MA TLABö Sim u link 对在不同输入电压参考信号和不同零矢 量分配方式下的调制信号和逆变器输出

DC/DC and DC/AC PWM Converters This demonstration illustrates use of the Universal Bridge and Discrete PWM Pulse Generator blocks. It also demonstrates harmonic analysis of PWM waveforms using the Powergui/FFT tool.

PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM qu
