Elimination of an Electrolytic Capacitor in AC/DC Light-Emitting Diode (LED) Driver With High Input Power Factor and Constant Output Current (2012, methodology): “In [9] and [10], the third- and fifthharmonic signals are injected into the input current to reduce the peak-to-average ratio of the input power.”
Low-Frequency Power Decoupling in Single-Phase Applications: A Comprehensive Overview (2017, methodology): “Third harmonic injection proposed in [15] and [16].”
A Novel Passive Offline LED Driver With Long Lifetime (2010, background): “Although electronic LED drivers without using electrolytic capacitors have been proposed [4]–[6], the use of active power electronic switches requires extra control electronics and auxiliary power supplies that will increase circuit complexity and reduce system reliability.”
A Novel Valley-Fill SEPIC-Derived Power Supply Without Electrolytic Capacitor for LED Lighting Application (2012, background): “Much research has been directed toward power factor correction (PFC) topologies and control schemes [13]–[28] in LED application over the past decades.”
Feed-Forward Scheme for an Electrolytic Capacitor-Less AC/DC LED Driver to Reduce Output Current Ripple (2014, background): “In [12] and [13], the third and fifth harmonics are injected into the input current to reduce the peak-to-average ratio of the input pulsating power.”
