| Summary: | 碩士 === 國立交通大學 === 電機學院碩士在職專班電機與控制組 === 98 === This paper presents a practical design method for the critical-conduction-mode (CRM) power-factor-correction (PFC) converter with EMI filter design by using an interactive mathematical computation and documentation software, the MathCAD. The design of CRM PFC converter is an involved process and there is a need for practical design engineers to follow an interactive and intuitive design procedure. The selection of major power components with loss analysis of the CRM PFC converter has been described. The design of input differential-mode (DM) EMI filter for the reduction of total-harmonic-distortion (THD)
for line current has been developed in considerations of practical design limitations. Computer simulations have been carried out by using power electronic system simulation software, the PSIM, to verify the design results such as power factor and THD. An illustrated design rocedure
and analysis are presented with given design example by using the MathCAD to combine and analyze the results of design, simulation .and experiment.
