The main contribution of this paper is to show a new AC/DC converter based on the rearrangement of the flyback converter. The proposed circuit only manages part of the energy and the rest is delivered directly from the source to the load. Therefore, with the new topology, the efficiency is increased, and the stress of the components is reduced. The rearrangement consist of the secondary of the flyback is placed in parallel with the load, and this arrangement is connected in series with the primary side and the rectified voltage source. The re-arranged flyback is only a reductive topology and with no magnetic isolation. It was studied as a power supply for LEDs. A low frequency averaged analysis (LFAA) was used to determine the behavior of the proposed circuit and an equivalent circuit much easier to analyze was obtained. To validate the theoretical analysis, a design methodology was developed for the re-arranged flyback converter. The designed circuit was implemented in a 10 W prototype. Experimental results showed that the converter has a THDi = 21.7% and a PF = 0.9686.

This paper discusses the soft switching circuit—Boost-ZVT converter, and studies the role of Boost-ZVT converter in the factor correction circuit(PFC). Distinguished from the past Boost converter, the Boost-ZVT converter implements the main switch of the soft turn-off, reducing switching losses and improving the system efficiency. At last, Matlab software is carried out the main circuit simulation. The simulation results show that Boost-ZVT circuit has a good effect in PFC circuit design, and has a wide application in practical circuit design.
