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...

目前我有HV_SOLAR DC/DC和HV_SOLAR DC/AC两板子，但还没将DCDC boost converter与DC/AC inverter相接。请教各位，当我将HV_SOLAR DC/DC与DC/AC相连接，应该会产生DCDC的output voltage ripple是吧?那么TI在这两板子有做了什么样的控制让DC的output voltage ripple变小?我有观察到DC/...
Abstract: The bulky electrolytic capacitor is conventionally used to curb the output voltage ripple of output DC-link in the front-end PFC AC/DC converter, which is applied for the on-board charger of the electrical vehicle. Due to the drawbacks of electrolytic capacitor, such as the short ...
In order to avoid any dysfunction, the DC-link voltage has to be as constant as possible. To achieve this purpose, a high capacitance is inserted in parallel to the network. This paper shows relationship between DC-link voltage ripple and DC-link current ripple by using a simplified ...
Besides, when suffering the asymmetrical grid faults, the proposed control method could to some extent attenuate the double-line-frequency dc-link voltage ripple to keep the dc-link voltage in the safe operational range by shifting the double-line-frequency power ripple to the front-end dc input...

Reduction of DC-Link Voltage Ripple of Three-phase AC/DC Converter for Uninterruptible Power Supply by Applying Fuel Cell Conventional UPS(Uninterruptible Power Supply) using batteries for assisting the source is limited by the large volume and the life-time of battery. Moreover, voltage variation ...
Computationally very expensive circuit simulations are required to design the dc-link capacitance for automotive traction voltage source inverters. Thereby, the dc-link voltage ripple is, in contrast to grid connected inverters, the predominant dc-link capacitor design parameter in automotive inverters. ...
