Abstract

See full text

Embodiments of a synthetic test circuit for a valve performance test of high-voltage direct current (HVDC) are presented. In some embodiments, the synthetic test circuit comprises a resonance circuit configured to comprise a first test valve to test an operation of an inverter mode and a second test valve to test an operation of a rectifier mode. The synthetic test circuit may comprise a power supply (P/S) configured to provide the resonance circuit with an operating voltage. The synthetic test circuit may comprise a direct current/direct current (DC/DC) converter configured to bypass a DC offset current of the resonance circuit. The first test valve may be an inverter unit, which may have a positive DC current offset. Further, the second test valve may be a rectifier unit, which may have a negative DC current offset.
