摘要

The study of harmonic instabilities in an AC/DC power system is presented in this letter. An existing frequency domain methodology is modified to assess the phenomena produced by this harmonic interaction. A set of analytical equations is derived to compute the commutation time taking place in the single-phase converter. Suitable guidelines are suggested for effective overlap angle initializations. Test results are presented that demonstrate the effectiveness of the proposed methodology. Instabilities are shown to take place for given operating conditions.
