低NFoM器件在1 MHz 380 V-12 V DCX变换器中的共模EMI噪声分析与抑制

For the thriving information technology industrial applications, the series resonant converter (SRC) dc transformer (DCX) using integrated printed circuit board (PCB) windings is a preferred candidate because of its high efficiency and high power density characteristics by pushing the frequency to megahertz. However, the planar PCB transformer possesses large interwinding capacitance, which leads ...
