Abstract
The present invention provides to a default current testing method of the high voltage direct current converter valve composited by impulse voltage. The technical scheme of the invention composites the symmetrical positive and negative voltage and the impulse into asymmetric positive and negative high voltage, it makes the test valve voltage accurately achieve required peak value at the set time. The test circuit is simple relatively; the high voltage source of the default current test circuit is instead by surge generators. The test method is flexible, safe, and suitable for different DC project converter valves.
