In this paper, the energy conversion efficiency (ECE) and cost characteristics of three-phase photovoltaic (PV) inverters (3P-PVIs) are studied comprehensively based on the operating principles of topologies and with respect to various performance indicators such as semiconductor device count and utilization factors, semiconductor efficiency (SE), dc-bus capacitor and filter inductor voltage/current ripple factors. The evaluation of topologies are based on datasheet parameters and analytical results are provided for 50 kW, 100 kW, and 200 kW power ratings. Such an evaluation of topologies is beneficial to engineers to wisely choose the appropriate topology for both transformerless and transformer based PV systems and to design the inverter accordingly.

A DC Bus Capacitor Design Method for Various Inverter Applications
Hava, Ahmet Masum; Aban, Vahap Volkan (2012-09-20)
This paper involves the selection and sizing of the appropriate type of dc bus capacitor for various applications utilizing PWM operated three-phase voltage source inverters, such as battery operated systems, PV (photovoltaic) systems, UPSs, and motor drives. It classifies the power converter topologies based on dc bus ripple current frequency characteristics. A general approach for ripple current characterization is provided. Based on these characteristics, the two capacitor types suitable for this purpose...
Metal-Free Interconnecting Layer for Monolithic Perovskite/Organic Tandem Solar Cells with Enhanced Outdoor Stability
Xu, Han; Merino, Luis Torres; Koc, Mehmet; Aydin, Erkan; Zhumagali, Shynggys; Haque, Md Azimul; Yazmaciyan, Aren; Sharma, Anirudh; Villalva, Diego Rosas; Hernandez, Luis Huerta; De Bastiani, Michele; Babics, Maxime; Isikgor, Furkan H.; De Wolf, Stefaan; Yerci, Selçuk; Troughton, Joel; Baran, Derya (2022-11-28)
Photovoltaics with monolithically connected tandem architectures have the potential to achieve high efficiencies owing to enhanced spectral absorption and reduced thermal losses. To achieve this, photoactive layers with complementary absorption and interconnecting layers, which are robust, transparent, and energetically suitable, are essential. Here, we investigate a strategy to create an efficient, highly transparent, ohmic, and chemically robust interconnecting layer based on atomic layer-deposited tin ox...
High data rate X-band transmitter for low Earth orbit satellites
Sunay, Hacer K.; Ismailoglu, Neslin; Kirilmaz, Tunahan; Dudak, Celal; Sen, Ozlem A. (2007-04-26)
Main purpose of this study is to design a transmitter with data rates up to 100 Mbps, having QPSK/OQPSK modulation and 7 W (38.5 dBm) output power at 8.2 GHz. This output power satisfies the link budget for a low earth orbit (LEO) satellite at 700 km, utilizing required source-channel coding schemes in baseband for a BER performance of 10(-6). The modulation scheme of the transmitter can be selected as BPSK, QPSK or OQPSK. In addition to QPSK/OQPSK modulation scheme choice, the transmitter will have three d...
Design and implementation of a 200w microinverter for grid connected photovoltaic energy conversion system
Kavurucu, Semih; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2014)
As one type of the grid-connected photovoltaic energy conversion systems, micro-inverters (MI, also known as Module Integrated Inverters, MII) are typically designed for residential applications with energy capacities of 3-5 kW and less, in order to provide PV module level energy generation, plug-N-play operation, minimization of the shading effects occurring on the PV module, and flexibility of installation. For the micro-inverter system which can be designed employing variety of topologies, interleaving f...
Design of Grid Connected PWM Converters Considering Topology and PWM Methods for Low-Voltage Renewable Energy Applications
Kantar, Emre; Hava, Ahmet Masum (2014-05-21)
This paper assesses the feasibility three-phase PWM three-level voltage source converters (VSCs), namely NPC-type VSC (3L-NPC) and T-type VSC (3L-T) as alternatives to standard three-phase PWM two-level VSC (2L-VSC) for low-voltage grid interface applications, The topological performances are compared through a design algorithm regarding varying switching frequency, load condition, modulation index, and converter side inductance under distinct pulse-width modulation methods, Design of the LCL filter is also...
