| Zusammenfassung: | The invention relates to a power device dynamic on-resistance testing device and method, a first voltage source module performs voltage impact on a to-be-tested power device when a blocking module is on and the to-be-tested power device is in an off state, and an isolation module performs voltage isolation when the first voltage source module performs voltage impact on the to-be-tested power device. The second voltage source module transmits current to the first pole of the to-be-tested power device through the isolation module after the to-be-tested power device is conducted, and the voltage sampling module and the current sampling module carry out voltage acquisition and current acquisition respectively when the first voltage source module transmits the current to the second pole of the to-be-tested power device. The obtained voltage sampling data and the obtained current sampling data can be further used for calculating the dynamic on-resistance of the power device to be tested, dynamic on-resistance testi |
