A Flicker-Free Electrolytic Capacitor-Less AC–DC LED Driver [PDF]
IEEE Transactions on Power Electronics, 2012 The electrolytic capacitor is the key component that limits the operating lifetime of LED drivers. If an ac-dc LED driver with power factor correction (PFC) control is allowed to output a pulsating current for driving the LEDs, the electrolytic capacitor will no longer be required.

A plug-and-play ripple mitigation approach for DC-links in hybrid systems [PDF]
, 2016 © 2016 IEEE.In this paper, a plug-and-play ripple mitigation technique is proposed. It requires only the sensing of the DC-link voltage and can operate fully independently to remove the low-frequency voltage ripple. The proposed technique is nonintrusive
