摘要
Abstract—Data centers demand high-current, high-efficiency and low-cost power solutions. And the high frequency resonant converter is more attractive in industrial application because of its high power density and high efficiency. This paper presents a modular and linear extendable single-stage DCX with high voltage conversion ratio which based on high frequency LLC resonant converter. The converter using a planar matrix transformer has successfully achieved ZVS in the primary side as well as ZCS in the secondary side. Meanwhile, GaN devices are also applied due to their much lower parasitic capacitance compared to that of high voltage Si MOSFET. A 500 kHz, 400-6 V, 600 W isolated prototype with high conversion ratio has been built and tested as well, which achieved 91.1% peak efficiency.
