LLC resonant converter modelling
, 2014 Many of today's power converters use pulse-width modulation(PWM) techniques to regulate the circulating currents and voltages. A significant problem with most dc-dc converters is the increased power loss during switching. These devices typically operate in hard-switching mode which results in switching losses.
