“…LLC series resonant topology is easily to achieve Zero-Voltage-Switch ranging from no load to full load and this advantage makes LLC topology widely used in many kinds of power converters to get higher efficiency, higher power density and higher working frequency [1]. However, LLC topology works under PFM mode, this means that the output voltage noise will increase when LLC works at its lower switching frequency [2]. In order to meet the standard limits of output voltage ripple under different loads, the output of a general single-phase LLC switched-mode power supply (SMPS) needs lots of capacitors in parallel to keep output voltage ripple smaller [3].…”

“…In order to meet the standard limits of output voltage ripple under different loads, the output of a general single-phase LLC switched-mode power supply (SMPS) needs lots of capacitors in parallel to keep output voltage ripple smaller [3]. Especially, this problem becomes more serious when a LLC is used in a low-voltage high-current output field [2]. It's well known that the interleaving method is an effective way to restrain output ripple and has been commonly used in Buck power supply for CPU [4,5].…”

LLC series resonant topology has been widely adopted in many kinds of power converters for its high frequency, high efficiency and high power density advantages. However, the ordinary topology of a single-phase LLC is not fit to be used in low-voltage high-current output field for its relative larger output voltage ripple. In order to provide a low voltage and high current output using a LLC topology, a novel interleaving LLC switched-mode power supply design was proposed to reduce output voltage ripples ripple in this paper. This design used two hardware measures to automatically ensure a good load current sharing effect between two-branch LLC circuits and avoid the PFM difficulties of the active current sharing methods. The principles and design procedures of this novel LLC converter were introduced in detail and verified by Saber simulation results. A 1.5kW DC/DC prototype was built up in the end and the experiment results showed that a good current sharing performance was achieved.
