Abstract

The paper presented the perturbation on-time (POT) control technique to suppress the total harmonic distortion (THD) to improve the performance of the power factor correction (PFC) in the AC-DC converter. Simultaneously, it can improve the efficiency through the proposed inhibit time control (ITC) mechanism at low AC input voltage. The test circuit fabricated in TSMC 800V UHV process can show the highly-integrated PFC controller. Experimental results demonstrate low THD of 8%, which results in high PF of 99%. Besides, high efficiency of 95% can be ensured at the output power of 90W.
