“…The works in [17], [56], [61] use a different three-level dcdc converter for feeding high-power loads and also contribute to minimize power fluctuations in bipolar dc systems. The power circuit is presented in Figure 12(c), where it can be seen that the basic unit is composed by four switching devices and their corresponding free-wheeling diodes, along with an output inductor and the output filter capacitor.…”

Single-Switch Bipolar Output DC-DC Converter for Photovoltaic Application

Bipolar DC grids have become an adequate solution for high-power microgrids. This is mainly due to the fact that this configuration has a greater power transmission capacity. In bipolar DC grids, any distributed generation system can be connected through DC-DC converters, which must have a monopolar input and a bipolar output. In this paper, a DC-DC converter based on the combination of single-ended primary-inductor converter (SEPIC) and Ćuk converters is proposed, to connect a photovoltaic (PV) system to a bipolar DC grid. This topology has, as main advantages, a reduced number of components and a high efficiency. Furthermore, it can contribute to regulate/balance voltage in bipolar DC grids. To control the proposed converter, any of the techniques described in the literature and applied to converters of a single input and single output can be used. An experimental prototype of a DC-DC converter with bipolar output based on the combination of SEPIC and Ćuk converters was developed. On the other hand, a perturb and observe method (P and O) has been applied to control the converter and has allowed maximum power point tracking (MPPT). The combined converter was connected in island mode and in parallel with a bipolar DC microgrid. The obtained results have allowed to verify the behavior of the combined converter with the applied strategy.

“…Since this topology has two more components in the LCL resonant tank, the time domain analysis method described in the literature [6] is no longer applicable here. Therefore, the phasor method is adopted in this paper, which solves each sinusoidal variable at different frequencies and then The equivalent model shown in Figure 4, from which an LCL-DAB DC-DC converter can be regarded as a two port circuit, the input and output characteristics are expressed in Equation (1). Here we define the resonant frequency as s = 1∕…”

LCL-type resonant dual-active-bridge (LCL-DAB) DC-DC converters have more significant advantages in eliminating backflow power and achieving higher voltage gain compared with traditional dual active bridge (DAB) DC-DC converters. Therefore, LCL-DAB DC-DC converters have a broad application prospect in DC micro-grids, electric vehicles, uninterruptible power supplies etc. Since at this stage only a few researches on LCL-DAB DC-DC converters have been done, here, the specific system operation region with triplephase-shift (TPS) modulation scheme designed under no backflow power is presented. Furthermore, a dynamic compensation based feedforward control method under no backflow power is proposed, which enables the LCL-DAB DC-DC converter to operate under no backflow power in wide region and achieve outstanding dynamic performance against output/input disturbance. Finally, the experimental results verify the feasibility and effectiveness of the proposed control method.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
