Common-mode noiseFlyback converterParasitic capacitanceThis paper proposes a novel balanced bridgeless flyback power factor correction (PFC) rectifier to reduce common-mode noise. A high-frequency equivalent circuit with parasitic winding capacitors is presented and compared with that of conventional ...
Experimental results validate that both approaches can greatly reduce CM noise up to 30 dBmuV. The two approaches are compared in terms of both its effects on CM noise and their implementations. 展开 关键词: Balance bridgeless power factor correction (PFC) converter common mode (CM) noise ...
Common mode (CM) noise is substantially canceled in a switching power supply circuit such as a boost converter by providing a split inductor and analyzing the switching power supply circuit as a bridge circuit formed of the switch, portions of the split inductor and parasitic capacitances of resp...
IMPEDANCE During the deduction of common mode noise model of Boost PFC circuits [4], all the stray inductance and resistance in the wires or traces are ignored and all the stray capacitances are considered as lumped capacitances connected to the electric nodes in the circuits. For the ...

The component placement or board design also matters for a robustness to transient noise. The parasitic capaci- tance between one side of the driver to the other side of the driver should be minimized. Using a diagram from the Figure 6: Single-phase inverter with isolated gate drivers GND U1...
