In various industrial applications, the use of a power supply that uses a conventional diode single-phase rectifier topology results in high harmonic values in the electricity distribution system. One of the real impacts of this harmonic value is the heating of the electric power system equipment and power losses. High rms current values due to harmonics often cause problems in protection settings in addition to efficiency problems. The percentage value between the total harmonic component and the fundamental component is called THD (Total Harmonic Distortions). Therefore, in this study an asynchronous dc-dc boost converter is connected to the output side of a single-phase diode rectifier which is capable of improving power factor and low harmonics. So that a THD value of less than 15%, PF (Power Factor) = 0.92-1 and a sinusoidal input current can be obtained. The implementation results show that the PFC (Power Factor Correction) method can work well on single-phase diode rectifiers.

This paper proposes an LLC type AC/DC converter to achieve high efficiency for wide input voltage range. The proposed converter has four operating modes with different voltage gain characteristics depending on the ON/OFF state of the six switches. The proposed system achieves a wide range of voltage gain by switching between different operating modes. Consequently, the proposed system reduces the magnetizing current by designing a narrow voltage gain in each operating mode. Moreover, the proposed control method achieves power factor correction control of the input current and smooth transition between different operating modes. This paper analyzes the operation and voltage gain characteristics of the proposed converter. A design method to reduce the magnetizing current and the mode transition method is also explained. Based on the experimental results on a 200 W prototype, the basic operation of the proposed system is confirmed in the input voltage range of 100 V to 240 V. Furthermore, the total harmonic distortion (THD) of the input current up to the 40th order of the fundamental frequency is less than 5% across the entire input voltage range. The efficiency of the proposed system is more than 92.5% across the entire input voltage range.
