“…Multilevel inverters with only one DC source may be the most desirable topology. Recently [14] presented an inverter called a five-level-active-neutral-point-clamped with coupled inductor, which uses split of the DC-link capacitor. In [8] inverter was proposed using coupled inductors.…”

This paper suggests quinary asymmetric inverter with coupled inductors and transformer, and uses it in hybrid system including photovoltaic (PV) and wind. This inverter produces twenty-five-level voltage in addition to merits of multilevel inverter, has only one DC source. Then, it is adequate for hybrid systems, which prevents increasing DC-link and makes control of system easy. Proposed structure also provides isolation in the system and the switch numbers are reduced in this topology compared with other multilevel structures. In this system, battery is used as backup, where PV and wind have complementary nature. The performance of proposed inverter and hybrid system is validated with simulation results using MATLAB/SIMULINK software and experimental results based PCI-1716 data acquisition system.

“…The multi-level topology can improve the disadvantages of traditional 2-level, raise efficiency, reduce the volume of filter inductor. However, there are obvious disadvantages, such as too many components, complex control, it is difficult to promote broadly in the actual [1,2,3]. The interleaving technique is widely treated in the literature.…”

In this paper, a novel topology scheme of photovoltaic inverter is presented. The proposed topology employ the 4-terminal switch-network that consist of three interleaving parallel connection half-bridges and a three winding transformer into low voltage inverter to achieve a multilevel voltage. This new inverter increases the output power and reduce the volume of filter inductance. The operation principle and all switch modes are described in details. Meanwhile, the modulation method is also demonstrated to achieve operation. Finally, simulation and experiment results verify the theoretical analysis.

“…Multilevel converters are extensively used in high power systems because they can deal with higher voltages due to the fact that the voltage to be switched is shared among several semiconductors [1]- [3]. They also yield better output voltage spectra than two-level converters [4].…”

Abstract-Connecting legs in parallel in a voltage source inverter is a way to increase the output current and thus, its rated power. The connection can be made using either coupled or uncoupled inductors and achieving an even contribution to the output current from all the legs is a crucial issue. Circulating currents produce additional losses and stress to the power devices of the converter. Therefore, they should be controlled and minimized. An efficient technique to attain such a balance when coupled inductors are used is presented in this paper. The proposed technique can also be used when the inductors are uncoupled, since it is a particular case where the coupling coefficients are zero. This technique does not include proportionalintegral controllers and does not require any parameter tuning either. The exact control action needed to reach current balance is straightforwardly calculated and applied. Experimental results are shown in this paper to verify the efficiency of the proposed balancing method.
