利用分绕组配置降低共模噪声的非隔离DC-DC变换器

The common-mode (CM) noise in nonisolated dc-dc converters is mainly caused by the displacement current through the high dv/dt node in the circuit and the associated parasitic capacitance, and it may cause electromagnetic interference (EMI) to the surrounding equipments. To reduce the original CM noise and shrink the EMI filter size of non-isolated dc-dc converters, CM noise cancellation methods h...
