This letter presents a Space Vector Pulse Width Modulation (SVPWM) strategy for reducing the DC-link current harmonics in a multi- Voltage Source Inverter (VSI) topology with common DC-link bus. The DC current harmonic reduction is achieved by phase-shifting the PWM pattern of individual VSIs, with the inverters sharing the system total power. Simulation and experimental results are shown to validate the proposal.

Featured Application This topology is applied to photovoltaic generation conversion using multiple panels and a single magnetic core, using MPPT and obtaining an efficiency over 96%. DC-DC power converters have generated much interest, as they can be used in a wide range of applications. In micro-inverter applications, flyback topologies are a relevant research topic due to their efficiency and simplicity. On the other hand, solar photovoltaic (PV) systems are one of the fastest growing and most promising renewable energy sources in the world. A power electronic converter (either DC/DC or DC/AC) is needed to interface the PV array with the load/grid. In this paper, a modified interleaved-type step-up DC-DC flyback converter is presented for a PV application. The topology is based on a multi-winding flyback converter with N parallel connected inputs and a single output. Each input is supplied by an independent PV module, and a maximum power point tracking algorithm is implemented in each module to maximize solar energy harvesting. A single flyback transformer is used, and it manages only 1/N of the converter rated power, reducing the size of the magnetic core compared to other similar topologies. The design of the magnetic core is also presented in this work. Moreover, the proposed converter includes active snubber networks to increase the efficiency, consisting of a capacitor connected in series with a power switch, to protect the main switches from damaging dv/dt when returning part of the commutation energy back to the source. In this work, the operating principle of the topology is fully described on a mathematical basis, and an efficiency analysis is also included. The converter is simulated and experimentally validated with a 1 kW prototype considering three PV panels. The experimental results are in agreement with the simulations, verifying the feasibility of the proposal.

The development of distributed generation, mainly based on renewable energies, requires the design of control strategies to allow the regulation of electrical variables, such as power, voltage (V), and frequency (f), and the coordination of multiple generation units in microgrids or islanded systems. This paper presents a strategy to control the active and reactive power flow in the Point of Common Connection (PCC) of a renewable generation system operating in islanded mode. Voltage Source Converters (VSCs) are connected between individual generation units and the PCC to control the voltage and frequency. The voltage and frequency reference values are obtained from the P-V and Q-f droop characteristics curves, where P and Q are the active and reactive power supplied to the load, respectively. Proportional-Integral (PI) controllers process the voltage and frequency errors and set the reference currents (in the dq frame) to be imposed by each VSC. Simulation results considering high-power solar and wind generation systems are presented to validate the proposed control strategy.

The Modular Multilevel Converter (MMC) is one of the most practical topologies for integration of renewable energy power plants into the grid, through submarine HVDC cables and HVDC lines. Nonetheless, the MMC requires significant large DC storage capacitors. This work addresses the recently introduced Asymmetric Alternate Arm Converter (A3C), a hybrid MMC topology which uses modular arms only on the lower side of the main converter whereas the upper side uses only standard ON-OFF valves. The A3C offers a significant reduction in DC energy storage requirements and in the number of modules. In addition, it offers a less restricted operation than the Alternate Arm Converter (A2C), in terms of operating over a wide range of AC to DC voltage ratio, and the possibility of achieving both nearly sinusoidal AC current and nearly constant DC current. The principle of operation of the A3C, but in the inverter mode and using thyristor-based director switches, is revisited here and a suitable control strategy to demonstrate its operation is developed. Emphasis is place on switching off the thyristor valves in a soft commutation fashion. The method requires two A3C operating in interleaving fashion on the DC bus. Proposals are verified through simulation studies.

This paper presents a strategy to control the active and reactive power in the point of common connection (PCC) of a wind generation system operating in islanded mode. A full back-to-back voltage source converter (VSC) is connected between each wind generator and the PCC. The control scheme considers voltage and frequency regulation for each VSC. The voltage and frequency references are obtained from P-V and Q-f droop characteristics of the generators, where Q and P are the reactive and active power supplied by each VSC to the PCC. Proportional-integral (PI) controllers process the voltage and frequency errors and set reference currents (in d-q frame) to be imposed by the converter. The strategy has been validated by mean of simulations, and results are presented showing the performance of the control strategy proposed.

In this paper, a multiple drives solar-pumping system is presented. The system is based on a single-stage photovoltaic (PV) topology where an array of solar panels is connected to multiple inverters supplying equal centrifugal pumps. The inverters are operated to extract the maximum power from the PV system and a predictive control strategy for the machines currents is proposed. The performance of the system is verified via simulations.

Alternate arm converter with thyristor-based director switches

The Modular Multilevel Converter (MMC) is the choice topology for integration of renewable energy power plants into the grid, through submarine HVDC cables and HVDC lines. Notwithstanding, the MMC requires significant large DC storage capacitors to mitigate for the large power pulsations that result from the single-phase AC to DC conversion process in their arms. The Alternate Arm Converter (AAC), which combines MMC arms with conventional valves (Director Switch), has the potential to cut the number of modules to half of that of the conventional MMC. Further, it is capable of blocking DC faults, an appealing feature for future DC networks. However, the AAC incurs higher power losses than conventional MMC. This work proposes the use of thyristors, instead of IGBTs, to implement the DSs of the AAC. This reduces conduction losses in DSs by approximately a half and makes the AAC more comparable to the conventional MMC, in terms of power losses, but with the advantage of reduced DC energy storage requirements. The principle of operation of the AAC, considering thyristor based DSs, is revisited here and a suitable control strategy to demonstrate its basic operation is developed. Proposals are verified through simulation studies using a switching converter model. Results confirm feasibility of proposed thyristor based DS and good performance of the proposed AAC.
