“…Increased electrification, smart grid technology, and renewable power generation has brought to light the need for improved power electronics. These are required for an electrical grid which is more sustainable, flexible, reliable, and distributed [1,2]. As technologies like photovoltaics and electric vehicles become more common, the electronics for power conversion (DC-AC, AC-DC) must be able to handle larger power in order to control utility-scale energy [3].…”

As electricity grids become more renewable energy-compliant, there will be a need for novel semiconductors that can withstand high power, high voltage, and high temperatures. Wide band gap (WBG) semiconductors tend to exhibit large breakdown field, allowing high operating voltages. Currently explored WBG materials for power electronics are costly (GaN), difficult to synthesize as high-quality single crystals (SiC) and at scale (diamond, BN), have low thermal conductivity (β-Ga2O3), or cannot be suitably doped (AlN). We conduct a computational search for novel semiconductors across 1,340 known metal-oxides using first-principles calculations and existing transport models. We calculate the Baliga figure of merit (BFOM) and lattice thermal conductivity (κL) to identify top candidates for n-type power electronics. We find 40 mostly ternary oxides that have higher κL than β-Ga2O3 and higher n-type BFOM than SiC and GaN. Among these, several material classes emerge, including 2-2-7 stoichiometry thortveitites and pyrochlores, II-IV spinels, and calcite-type borates. Within these classes, we propose In2Ge2O7, Mg2GeO4, and InBO3 as they are the most favorable for n-type doping based on our preliminary evaluation and could be grown as single crystals or thin film heterostructures. These materials could help advance power electronic devices for the future grid.

This paper investigates the impact of different converter topologies and mission profiles on the reliability of dc/dc boost-type PV converters. The reliability of three boosttype converters with the same input/output specifications is modeled employing a mission profile-based reliability evaluation method considering non-constant failure rate for the electrical components. This study identifies the contribution of active and passive components on the converter reliability for identifying the most failure prone components. Furthermore, the applicability of converter structures for different climate conditions is demonstrated seen from the reliability point of view.

“…In these systems, DC/DC, AC/DC (rectifier) and DC/AC (inverter) power converters are utilized. DC/DC converters are used as maximum power point tracker, voltage booster and battery charger/discharger in photovoltaic systems [2], [3]. AC/DC converters control the extracted power from wind turbine or regulate DC bus voltage [4].…”

In this paper, realization of three-phase gridconnected inverter controlled with dSPACE DS1103 control board is presented. Detailed information about power circuit, sensor board, signal isolation board and DS1103 is given in the paper. The inverter is controlled with DS1103 control board, programming the DSP via MATLAB/Simulink. Connection between the developed control algorithm in Simulink and experimental setup is made with installed DS1103 tools in Simulink. Space vector pulse width modulation technique in dq synchronous reference frame is used to control the threephase inverter. The transferred power to grid is 10 kW via three-phase inverter. The injected grid current has 3.59% THD value with 9 kHz switching frequency and 3 mH filter inductance.
