LLC RESONANT CONVERTER AND A DISPLAY DEVICE, CAPABLE OF FEEDBACKING A CURRENT BASED ON A SMALL SIGNAL ANALYSIS

摘要

PURPOSE: An LLC resonant converter and a display device are provided to implement rapid response by detecting the change of a resonant switching current and feedbacking it.;CONSTITUTION: In an LLC resonant converter and a display device, a switching unit(941) operates according to a switching control signal. An LCC resonant tank(942) transfer the energy of a primary winding to a secondary winding according to the switching of a switching unit. A rectifying smoothing unit converts the voltage induced from the secondary winding to DC current. A voltage compensation unit(944) maintains the output voltage of the rectifying smoothing unit.;COPYRIGHT KIPO 2011
