利用谐振并联电路抑制平衡变换器的电磁干扰噪声

Balanced converter is an effective way to reduce the CM noise. However, the parasitic capacitance between the switch and heat sink leads to resonant problems, resulting in high noise in certain frequency range. This paper proposes a novel coupled inductor structure based on the balanced technique for the Boost converter to further reduce the CM noise at certain frequency range. A shunt resonant pa...
