Abstract

A three-phase three-level four-wire boundary mode PFC converter (TTFB PFC) is presented firstly. Based on the TTFB PFC circuit, a novel converter integrated with PFC & DC/DC functions is proposed, which has the merits of low cost and high power density, and also can meet the international standard to input current harmonic of electrical equipments. Principle of the integrated converter is analyzed and experimental results are also given. From the experimental results, when in normal condition the total harmonic distortion (THD) of input currents and efficiency of the TTFB PFC converter are 7.2% and 97.2% respectively.
