How To Analyze DC Circuit in the Design of Printed Circuit Board?

Nov 27, 2017

DC equivalent circuit analysis is a method of analysis to separate the analyzed circuit of DC system in DC equivalent analysis, without considering the processing circuit of input AC signal, only consider the relationship between the power supply caused by direct current voltage static DC current and voltage. In the DC equivalent analysis, the DC equivalent circuit diagram should be drawn first. When drawing the DC equivalent circuit diagram, the following principles should be followed: the capacitor should be treated by open circuit, the inductor that can ignore the DC resistance should be considered as a short circuit, and the inductor with no resistance components can be considered as resistor. The voltage after the buck decoupling is used as the supply voltage of the equivalent circuit, and the anti bias state semiconductor diode is regarded as open circuit.
