Electronic price computing scale conduction EMI noise diagnosis and inhibition

Point to a model electronic price computing scale conduction EMI noise excess problem, this article proposes a kind of noise separation network optimization structure and inductor-capacitor optimization filter design. Noise inhibition result indicates that this method not only satisfies electronic price computing scale, but also this optimization filter reduces the parasitic effects, and reduces the economic costs.
