Magnetic integration technology is an important approach to achieve high power density because it reduces the number, volume and weight of magnetic components in power converts. A planar transformer structure and parameter design method are proposed based on matrix magnetic integration schemes for CLLLC resonant converters, such as large volume, small leakage inductance adjustment rage, etc. The structure adopts a combined winding placement method, integrating the primary and secondary resonant inductor, excitation inductor, and transformer into one magnetic component. The primary and secondary resonant inductance, excitation inductance, and transformer turn ratio adjustment and control are achieved by controlling the cross-sectional area of the magnetic core column, the combination of winding turns, and the air gap. The experimental results show that compared with discrete magnetic components, the proposed matrix magnetic integrated structure has the same function and effectively reduces the volume and weight of magnetic components, which can provide a reference for the lightweight and miniaturized design of servo power supplies.
