The circuit topology is derived by integrating a boost converter and a buck converter. The boost converter performs the function of power-factor correction (PFC) to obtain high power factor and low current harmonics at the input line. The buck converter further regulates the dc-link voltage to provide a stable dc output voltage. Without using any active- clamp circuit or snubber circuit, the active switches of the proposed converter can achieve zero- voltage switching-on (ZVS) transition together with high power factor that satisfies the IEC 61000-3- 2 standards over a wide load range from 30% to 100% rated power. The steady-state analysis is developed and a design example is provided. A prototype circuit of 60 W was built and tested. Experimental results verify the feasibility of the proposed circuit with satisfactory performance.

In order to achieve unity power factor, it requires the output voltage of both converter be higher than the amplitude of the ac line voltage. Therefore, high-power-factor ac/dc converters usually consist of two stages. The first one is an ac-to-dc stage which performs the function of PFC and the second one is a dc-to-dc stage used to supply stable dc voltage to the load. In spite of their good performance, the circuit efficiency of two-stage approaches is impaired since it takes two energy- conversion processes which inevitably introduce some losses including switching loss, conduction loss and magnetic core loss. Besides the two-stage approaches, the Cuk and the Sepic converters can also achieve high power factor and regulate the output voltage . The Cuk converter is a combination of boost and buck converter and the Sepic converter is a combination of boost and buck-boost converter. Both converters have the advantage of simple circuit topology since they only use one active switch and one diode. High power factor can be achieved by operating the boost converter either at DCM or continuous conduction mode (CCM). The buck or buckboost converter can further regulate the output voltage of the boost converter to obtain a smooth dc voltage. However, the output voltage of the boost converter is usually higher than the amplitude of the AC line voltage. Before turning on the active switch, the output voltage is across its parasitic capacitor.

The boost, Cuk and Sepic converters can also be operated at critical conduction mode (CRM) to obtain high power factor. Synchronous rectification (SR) technique is popularly applied while operating these converters at CRM. A MOSFET is used to replace the freewheel diode, and hence the conduction loss is effectively reduced.

The boost converter is composed of Lp, DS1, S2 and Cdc and the buck converter is composed of Lb, D5, DS2, S1 and Co. Both converters operate at a high-switching frequency, fs. The boost converter performs the function of PFC. When it operates at discontinuous-conduction mode (DCM), the average value of its inductor current in every high-switching cycle is approximately a sinusoidal function. The low pass filter is used to remove the high frequency current of the inductor current.

By freewheeling the inductor currents of the converters to flow through each of the intrinsic diodes of the MOSFETs, both active switches are turned on at ZVS. It assures high circuit efficiency. The boost converter is designed to operate at DCM to perform the function of PFC. It requires that dclink voltage should be higher than two times of the amplitude of input voltage. The buck converter further regulates the dc-link voltage to obtain a stable dc voltage with low ripple. Experimental results based on the 60-W prototype circuit show that high circuit efficiency, high power factor and low THDi can be achieved over a wide load range. A circuit efficiency of 94.8%, power factor of 0.995 and a THDi of 9.25% are measured at rated output power.
