Abstract :
LLC series resonant converter has many unique characteristics and improvements over PWM topologies. However, many output capacitors are needed in parallel to satisfy an output voltage ripple and a rated ripple current of the capacitors. This paper is dealt with a novel two phase interleaved LLC resonant converter using a phase of the resonant capacitor. The proposed converter satisfies low output-voltage ripple requirement and meets the rated ripple of output capacitor´s current with few output capacitors. The operation and features is considered in detail and a prototype with a 12 V-100 A output is investigated.
