Increasing use of rectifiers causes harmonics pollution in networks. So use of power factor correction (PFC) in converters is inevitable. For reducing weight and volume of converters, designers try to increase switching frequency. The switching losses and conduction losses are two sources of losses in the switching power converter. Thus to reduce these losses, a new bridgeless soft switching PFC converter without any extra switch is introduced in this paper. A passive lossless snubber is used for bridgeless boost converter which can reduce the switching and conduction losses simultaneously. The proposed converter provides soft switching condition for all semiconductor elements. The proposed converter is analyzed theoretically and the design consideration are given. Then for a design example, the values of circuit elements are calculated. It is simulated by PSIM. Finally the efficiency comparison that is simulated by ORCAD software is presented. It shows that the proposed converter improve the efficiency at the nominal load in comparison with hard switching counterpart.

“…Recently, to increase the efficiency of the boost PFC converters, soft switching techniques has been applied [5][6]. Soft switching techniques reduce the switching losses [7][8][9][10][11][12]. These techniques can be classified into two categories, zero current switching (ZCS) and zero voltage switching (ZVS).…”

“…Researchers and engineers have made efforts to improve the performance of PFCs, primarily paying attention to high efficiency, high power density and total harmonic distortion (THD) [3,4,5,6,7,8] related to the power factor and EMI. The trend in PFC development is to apply fewer components while achieving better performance and satisfying the proposed requirements.…”

A PFC circuit for applications higher than 2 kW is generally configured by an interleaved structure, which reduces component stress and the ripple of inductor currents and output voltage. However, when implemented with GaN HEMT and controlled by a double sliding mode, a high-power totem pole PFC could achieve better performance without an interleaved structure.

“…Power factor correction (PFC) is an essential element ensuring that AC-DC power converters comply with grid codes, such as the IEC61000-3-2 harmonic limits [1][2][3][4][5]. In-phase sinusoidal waveforms in current and voltage draw second-order reactive power that can cause second-order ripple in the DC-link voltage in single-phase applications.…”

Continuous conduction mode power factor correction AC-DC converters are widely employed as the front stage in power supplies with medium or high output power. The second-order reactive input power in single-phase systems causes second-order ripple in the DC-link voltage. The speed of voltage regulation is thus limited by the second-order frequency in seeking to achieve low distorted input current. This study presents a fast second-order voltage estimation method, wherein an integrator is used for the estimation of second-order voltage ripple to obtain rapid voltage feedback without ripple and thereby cope with the limitations imposed by the second-order frequency. This approach greatly expands the bandwidth of the voltage control loop beyond the second-order frequency while reducing the total harmonic distortion associated with the input current. This also makes it possible to reduce the DC capacitance to reduce costs. The authors opted for full digital control using a TI F28335 DSP IC, in conjunction with feedback plus feedforward control to facilitate the design of the current loop. A feedback current corrector is used to reduce distortion associated with the input current over a wide load range. The effectiveness of the proposed control method was confirmed with some simulation and experimental results.
