Multi-input push-pull converter with multiple-primary-winding is suitable in low and medium-power applications. However, with the increase of input sources, the number of the primary windings and switches increases as well. Based on Pulsating Voltage Source Cells (PVSCs) combination principle, this paper replaces the input voltage source of the single-input push-pull converter with the series or parallel-connected non-isolated pulsating voltage source cells (PVSCs). Thus a family of single-primary-winding (SPW) voltage-fed multi-input push-pull converters can be proposed. Compared with traditional multi-input converters, they have a form of single-Primary-Winding, and therefore we could greatly reduce the size and cost. Since the configuration of a double-input Buck dc/dc converter is very simple, it is chosen as an example in this paper to analysis this MIC. The operation principle and control strategy are illustrated. Finally, simulation and experimental results are presented to verify the correctness of theoretical analysis

A new converter for the non-isolated PV (photovoltaic) system is presented in this paper. It has the advantage that the input terminal of the proposed converter is connected to the output negative terminal. In this way, the parasitic capacitance is bypassed to eliminate the undesirable leakage current. The proposed converter can achieve the step-up voltage with four switches only. Aside from that, the carried-based modulation is used, and the control structure is simple. The article analyzes the working modes and control strategy of the proposed converter. In addition, a comparative analysis is provided. The feasibility of the proposed converter under different working modes is verified by simulation. Finally, the digital control prototype with DSP plus FPGA is established and the experimental tests are carried out. The experimental results verify the effectiveness of the proposed converter.

Dc Voltage

Direct current (dc) voltage sources are one of the voltage sources most widely used for various purposes. Dc voltage can be obtained from a dc generator or by converting an ac voltage into a dc voltage using a power converter. There are several dc voltage levels that are commonly used by electrical and electronic equipment. To get a dc voltage that can be used for various equipment, then a dc voltage source must be varied according to the required. One way to get a variable dc voltage is to use a dc-dc converter. This research proposes a dc-dc boost converter that can increase the dc voltage with varying outputs. The boost converter is proposed using Arduino Uno as a controller with an input voltage of 12 volts. The converter output voltage regulation is implemented through Arduino programming using Matlab simulink. The experimental results show that the boost converter designed in this study has worked well as intended. This can be seen from the boost converter output voltage which is in accordance with the reference voltage entered in the Matlab simulink program

The aim of the paper is to research possibility to use a "hexagon" scheme static frequency converter as controlled intersystem link for two parallel operating power systems with different operating frequencies, or standards for frequency stabilization. The paper aims to study the transformer device operating characteristics that implements the output voltage phase circular rotation principle relative to the input voltage and controlled by power electronics. This goal is achieved through the elaborated "rough" device control strategy, which made it possible to provide controlled AC intersystem link of asynchronous power systems without the use of additional harmonic filters and dampers. Two sectioning modes of adjusting windings were used to apply 24 and 48 position laws of the converter "fine" control. The most significant results are the new technical solution of the frequency converter, as well as the "rough" control strategy. To assess the conversion quality, indicators were used that characterize the degree of stability of the transmitted power and the harmonic distortion of the current. The computational experiments results have shown the effectiveness of the proposed "rough" control strategy. It is proved that 48-position sectioning of the "fine" regulation winding can significantly improve the quality of conversion compare to 24-position. The obtained results significance is that developed technical solution provides acceptable indicators of the frequency conversion quality and transmitted active power stability. In addition, the use of the proposed converter technical solution can significantly reduce the number of windings and control means compare to previously ones studied by the authors

Background: With the increasing development of voltage source converter based high voltage direct current (HVDC), it will become a reality to interconnect different DC networks into DC grid with DC-DC converters. Methods: In this paper, three operation scenarios for the DC grid with DC-DC converters are proposed, by which the DC networks can reinforce each other with relative independence. In order to achieve the flexible switching of the proposed scenarios, the DC-DC combined control and principle of parameter selection are presented. In addition, two coordination controls for different scenarios are given to optimize the distribution of unbalanced power when the disturbances occur in the grid. With the proposed scenarios and control strategy, the impacts caused by the disturbances are alleviated and the uninterrupted operation of the grid is guaranteed. Results: A simulation model is established on the PSCAD/EMTDC and the simulation results verify the effectiveness of the proposed operation scenarios and control strategy. Conclusion: Finally, the effectiveness of the proposed operation scenarios and control strategy is verified by the simulation results in PSCAD/EMTDC.
