Method for Measuring Resonant Frequency of Snubber Circuits

Resonant frequency measurement of standardized snubber circuits is accomplished with a frequency bridge.

A resistor 10 of same identical kind that is used in the standardized snubber circuits, e.g., circuit S, is connected as a reference resistor in a leg of a standard Wheatstone Bridge 20. As such, resistor 10 matches the resistor characteristics of the resistor component Rs of the snubber circuits S to be measured.

In operation, each circuit S is connected to the test terminals 11 of the opposite leg of the bridge 20. The bridge 20 is then balanced by adjusting the frequency of adjustable frequency signal generator 12 until a null is obtained in the meter or oscilloscope 13 connected to the output of the bridge 20. The setting of the generator 12 is the resonant frequency of the circuit S being measured when this occurs.
