The maximum of voltage switching ripple is also derived in order to help with choice of the dc-link capacitor. The two most popular inverter modulation techniques are considered: sinusoidal PWM and centered PWM (CPWM, equivalent to space vector modulation, SVM). A comparison between them is ...
BOSHIDA DC电源模块是一种电子设备,用于将交流电(AC)转换为直流电(DC)供电给其他电子设备。关键参数对于了解电源模块的性能和适用范围非常重要。以下是一些常见的关键参数及其解读: 1. 输出电压(Output Voltage):指电源模块输出的直流电的电压水平。该参数通常以伏特(V)为单位。用户需要根据自己设备的电源要求选择与之...
This paper presents a dc-link voltage ripple compensation method for flying-capacitor (FC)-based active neutral- point-clamped multilevel converters operating under selective harmonic elimination pulsewidth modulation. The method is based on feedforward modifcation of the modulation index according to th...

In this paper several new techniques to reject dc-link voltage ripple in PWM inverters are examined in detail. It is demonstrated how continuous elimination of harmonics is achieved at the inverter output while simultaneously rejecting the dc-link voltage ripple. Thus with the proposed techniques it...
