boundary conduction mode controlled power factor corrector with line voltage recovery and total harmonic distortion improvement techniques
IEEE Transactions on Industrial Electronics, 2014Co-Authors: Chunyen Chen, Jenchieh Tsai, Yiting Chen, Kehorng ChenAbstract:The proposed line voltage recovery (LVR) and the total harmonic distortion improvement (THDI) technique improve power factor (PF) and total harmonic distortion (THD) over a wide line voltage range in boundary conduction mode controlled power factor corrector (PFC). The LVR detects the input line root-mean-square voltage to generate the digital equivalent code to the THDI for optimizing the THD by tuning the on-time value at different line voltages. In addition, the LVR and the THDI provide a Feedforward Path to reduce the ripple of the feedback voltage for further improving the THD. Therefore, the PFC controller can keep high PF and low THD over a wide line voltage. Experimental results demonstrate that the peak PF value is 0.998 and the minimum THD is 1.7% by the test circuit fabricated in a TSMC 800-V ultrahigh-voltage process with the universal line voltage range of 90-264 V.

high pf and ultra low thd power factor correction controller by sinusoidal wave synthesis and optimized thd control
International Symposium on Circuits and Systems, 2013Co-Authors: Chihwei Chang, Chialung Ni, Jenchieh Tsai, Longder Chen, Yiting Chen, Chunyen Chen, Kehorng Chen, Chengchen YangAbstract:The proposed sinusoidal-wave synthesis (SWS) and the optimized THD control (OTC) improve power factor (PF) and total harmonic distortion (THD) over a wide line voltage range. The SWS detects the input line root-mean-square (rms) voltage to generate the digital equivalent code to the OTC for optimizing the THD by tuning the on-time value. Besides, the SWS and the OTC provide a Feedforward Path to reduce the ripple of the feedback voltage for further improving the THD. Therefore, the PFC converter can keep high PF and low THD over a wide line voltage. Experimental results demonstrate the PF is higher than 0.99 and the THD is 1.7% at VAC of 90-110V by the test circuit fabricated in TSMC 800V UHV process.
