Series resonance voltage withstand test device

The utility model discloses a series resonance voltage withstand test device. A capacitor and a reactor of a test object are in series resonance connection, a high-voltage bleeder is in parallel connection with the test object, and the output of a variable-frequency power supply is coupled to a series resonance circuit by a driver transformer. A lower output voltage of the variable-frequency power supply can produce a higher testing voltage on the test object by circuit resonance.
