In order to improve dynamic performance to load variation of PFC circuit, a digital PFC algorithm with fast dynamic response is proposed in bridgeless boost PFC. The proposed algorithm improves dynamic response by increasing voltage loop bandwidth, and uses vector rotation scheme to generate compensating harmonic signal which counteracts second order harmonic resulted from increased voltage loop bandwidth...
Hybrid power control system (HPCS) can be considered a newly established branch in the research of power system. The concept, theory framework and cases of HPCS are introduced in the paper. In particular, the hybrid automatic voltage control (HAVC) illustrated in the paper has successfully optimized the quality, stability and operational cost of the power system. The discrete events are taken as the...
