“…With the excessive burning of coal, oil and natural gas in the modern industrial society, the greenhouse effect caused by the carbon dioxide gas entering the atmosphere has had a huge impact on the environment and climate,domestic and foreign attention to clean energy such as wind energy, tidal energy, and solar energy has been increasing, of which the DC-DC converter is an important part of converting clean energy into social productivity.Push-pull forward converters are widely used in low-voltage and high-current applications due to their small number of switches and isolation [1][2][3] .…”

Push forward converter is constrained by its switching loss under high frequency conditions, so it has to use heat sink to increase the volume of the converter, which is contrary to the design concept of small volume and high power density. Based on the traditional push-pull forward converter, this paper adopts phase-shifting control to realize ZVS of the primary side switch through LC resonance generated by the parallel capacitor of the primary side switch, the primary side leakage inductance and the secondary side filter inductance. At the same time, the dead time is set by calculating the duration of each mode in half a cycle. Finally, saber simulation is used to verify the feasibility of realizing ZVS of the push-pull forward converter, so as to provide a basis for the high power It provides a reference for the application under high frequency conditions.

“…Therefore, another converter is used after PFC stage to regulate the final output voltage. This structure is known as two‐stage structure, which is not optimal and cost effective for low power applications [3, 4]. Thus, for low power applications, typically, these two stages are merged together to use only one switch.…”

“…An active clamp in [9] is applied to provide soft switching condition, but two switches are required and the structure is not cost effective for low power application. All of the above mentioned structures, except [4] and [5], have dead angle problem in their input current resulting in high THD. In other words, during the zero crossing instant of the input voltage, the input current is zero and not shaped.…”

Here, a new single stage single switch soft switching PFC (power factor correction) converter is presented and analysed. The proposed converter combines buck AC‐DC converter and forward DC‐DC converter and applies an auxiliary circuit to eliminate input current dead angle. Furthermore, soft switching is attained and switching losses are eliminated resulting in high efficiency. Another merit of the proposed converter is the partial direct transmission of input power to the output that helps to improve efficiency. Experimental results are presented which justify the above mentioned points and show less than 5% THD in the nominal load. Comparison with other similar single stage PFC converters is performed and shows the proposed converter provides the lowest THD while high efficiency is attained.
