7.2 kV Three-Port SiC Single-Stage Current-Source Solid-State Transformer With 90 kV Lightning Protection

Electrochemical etching modes of 4H-SiC in KOH solutions

“…These properties make SiC an attractive candidate for various applications in electronics and optoelectronics. The corresponding SiC semiconductor devices exhibit favorable properties, including high voltage resistance and high-temperature resistance, radiation resistance, fast response time, and high reliability, and they have great potential for development [1][2][3][4][5]. However, the chemical and * Authors to whom any correspondence should be addressed.…”

Power Loss Minimization in Smart Transformer Enabled Low Voltage Islanded Meshed Hybrid Microgrid

“…All the remaining buses are considered as load buses. The load bus power at each load bus in LVac network (P lbac ) is given in (12).…”

“…Researchers have also explored various configurations of ST for improved integration of renewable sources into the grid. In [12], a SiC based single stage ST is proposed with superior features like single stage operation, buffer port for active power decoupling, lightning protection, modular structure and soft switching capabilities. A semimodular structure for ST is proposed in [13] which helps in reducing number of semiconductor devices in the overall ST.…”
