“…For this reason, a new flying capacitor inverter topology shown in Fig.3 is presented in (Radermacher et al 2004). Such a topology can operate either with three separate DC sources, which can be obtained through a set of PV arrays, or from a unique DC source with additional circuitry.…”

In this paper, a novel four-level flying capacitor inverter and its comparison with the conventional flying capacitor topology in terms of THD analysis are proposed. This new topology have some advantages over conventional one as following: The blocking voltages are the same for all switches used in the configuration, there is no need for capacitor midpoint connection and this eliminates low frequency current which circulate in dc-link capacitors, and the number of flying capacitor is reduced as compared with conventional form of it. The operation of the topology, modulation strategy, simulation results, and THD analysis for the output waveforms are presented in this paper.Article History: Received: 17th July 2017; Received: October 14th 2017; Accepted: Januari 18th 2018; Available onlineHow to Cite This Article: Gülpınar, F., Sarı, F., and Uzun, Y.

“…This topology has six semiconductor switches. It is clear, in this topology, the average number of semiconductors in the current path is lower, since the losses depend mainly on the number of semiconductors used, the modified version of NPC topology has better efficiency [70][71][72]. Among the soft switching scheme available in literature, the topology illustrated in Fig.…”

“…More recently, multi-level converters have found acceptance in low power systems, especially in photovoltaic applications, since it is possible to generate high quality voltage waveforms with semiconductor switches operating at a frequency near the fundamental [11]. DC-AC multi-level converters for single-phase output has also been explored also explored in the technical literature due to its importance in low power applications [12][13][14][15][16][17]. For instance, [18] proposed a single-phase multilevel converter for application in electrified railway, while [19] proposed a family of single-phase multi-level inverters with the same number of switching devices as in the conventional topology but without clamping diodes and flying capacitors.…”

-This paper proposes a grid-tied single-phase photovoltaic (PV) microinverter consisting of five-level fourswitch (5L-4S) DC-AC converter fed by an isolated fly-back DC-DC converter. The microinverter utilizes a split-coil inductor to produce five levels of pulse width modulation (PWM) compared to the three levels of PWM using conventional four-switch topologies. These implementations reduce losses by up to 39% compared to a conventional topology. The results show that the proposed design improves performance throughout the switching frequency spectra with various loads. The theoretical expectations are validated with simulation and experimental results.
