摘要

Reliability of the Power Factor Correction (PFC) system was improved by fast transient response using the proposed triple loop modulation (TLM). Low bandwidth of less than 20 Hz that rejects AC source of 60/120 Hz coupling deteriorated system reliability in case of output load variation. The proposed TLM can automatically adjust bandwidth to rapidly increase or decrease inductor current in order to shorten transient response time. In steady state, system stability can be guaranteed by low-frequency compensation pole without being affected by TLM. The test circuit fabricated in VIS 500 V UHV LDMOS process demonstrated the performance of the highly-integrated PFC controller with the proposed TLM. Experimental results showed that the PFC system with TLM has high PF of 99%, high efficiency of 95%, and high power driving capability of about 90 W. The improvement in transient response is twofold faster than conventional PFC design with output load variation from 90W to 45 W and vice versa.
