“…Such systems can increase the value of grid power transfer capability, stability, and controllability of grid operation, through series and shunt power compensation. The third area of possible TI applications concerns AC/DC, DC/AC, and DC/DC converters, which allow for shaping of the converter frequency characteristics [7][8][9][10]. However, Section 2 of this work focuses mainly on the possibility of application of the TI devices in the first group of power electrical systems mentioned above.…”

This work is devoted to possible implementation of tunable magnetic devices in electrical systems with adaptive properties. The basic idea, underlying operation of the presented magnetic device, depends on interaction of two (or more) magnetic fluxes in a quasi-linear range of ferromagnetic core characteristics. This is a new approach to the design of such magnetic elements; typically, saturation phenomenon of the ferromagnetic core of an inductor is used to change a value of its inductance. The good examples of adaptive electrical power systems can be devices for improving a quality of electrical energy. When used in compensators of reactive and a distortion power (or a reactive power only), tunable magnetic devices clearly offer wider possibilities for the compensation, compared to solutions, using compensators based on fixed magnetic elements. However, the application of the proposed tunable device in an adaptive compensator is only one example of its possible use in an electrical power area. In this work, the following issues are presented: exemplary solution of the adaptive passive compensator, basics of operation of tunable magnetic device, and test results of the experimental model of an electrical system with such a device.

“…In order for the problem of harmonic pollution to be solved, the active power factor correction (PFC) technique is the most suitable method because it increases the input power factor (PF) and reduces input current harmonic distortion [3]. Common current mode control methods include peak current control and average current control methods.…”

In this study, a new control strategy was proposed to improve transient response and the input current harmonic distortion of power factor correction (PFC) regulators operating in an average current mode. The proposed technique required only two additional gain selectors and a peak detector circuit on the feedforward voltage loop and output voltage feedback loops. It provided a direct reading for the average voltage value of feedback control loops and the peak voltage of feedforward control loops, producing PFC boost regulators with fast dynamic responses and low-input current harmonic distortion. The use of digital potentiometers for directly changing the gain of control loops did not require any divider or squarer to reduce the complexity of control circuits. The operating principles and control strategies of 300 W boost PFC with the new control strategy are presented with detailed analysis and discussion. The experimental results were satisfactory.

“…To improve the input PF and input current harmonics of the conventional buck PFC converter, some new control methods and new topologies are proposed [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”

“…Amongst them, buck PFC converter is a good choice especially for a broad range of ac–dc applications due to its several advantages such as high efficiency, cost reduction, low output voltage and lifetime improvement. Moreover, owing to the advantage of being suitable for universal input, buck PFC converter is often used as a pre‐regulator [17–37].…”

“…The single‐stage integration of a buck PFC and a tapped buck dc/dc converter is presented for offline power supply of LED lighting [32]. The work in [33] proposes an adaptive slope compensation method into the digital clamping current control at universal input voltages to improve the PF and the total harmonic distortion (THD). A novel bridgeless buck PFC converter with only half dead zones is put forward in [34], to realise high PF.…”

Nowadays, low power factor (PF) is a serious problem that has gained more importance in power electronics area. In this study, a unity PF control (UPC) strategy for boundary conduction mode (BCM) buck-buck/boost PF correction converter is proposed. The proposed control strategy can achieve high PF and low total harmonic distortion by utilising the input and output voltages to modulate the on-time of both buck and buck/boost switches. The operating principles and comparative analysis of BCM buck-buck/boost converter with conventional non-UPC and UPC are analysed. For verifying the effectiveness of the proposed control strategy, the experimental verifications are carried out from a 100 W universal input prototype.
