Impedance Measurement on PCB Using Shunt-Through Method with Short Jig

This letter proposes a measurement method for the parasitic components on a PCB for a high-frequency inverter circuit to estimate the DC-bus parameters on the PCB accurately. The proposed method enables accurate measurement with a short jig that applies the shunt-through method for the DC-bus parame...

Zusammenfassung:This letter proposes a measurement method for the parasitic components on a PCB for a high-frequency inverter circuit to estimate the DC-bus parameters on the PCB accurately. The proposed method enables accurate measurement with a short jig that applies the shunt-through method for the DC-bus parameter evaluations. The validity of the proposed method is further demonstrated by comparisons with the results of electromagnetic analysis.
