Static B10 Lifetime SiC-MOSFET PV Inverter: Reliability Simulation for India

A 2026 simulation dataset from figshare by Sainadh Singh Kshatri models the reliability of a 3 kW grid-connected photovoltaic inverter. It compares the B10 lifetime—the time by which 10% of units are expected to fail—for inverters using conventional IGBT, super junction MOSFET, silicon carbide MOSFET, and gallium nitride HEMT technologies under a one-minute resolution yearly mission profile for Narsapur, India. The Monte Carlo simulation produced 10,000 samples with 5% parameter variation to model lifetime using a two-parameter Weibull distribution.

Use Cases

• Compare inverter component reliability based on B10 lifetime calculations for different semiconductor technologies.
• Model power electronic device degradation based on mission profile data including solar irradiance and ambient temperature.
• Analyze the impact of wide-bandgap semiconductors on performance metrics like PV power, switch losses, and inverter efficiency.
• Validate reliability simulation methodologies using Monte Carlo sampling and Weibull distribution fitting.

Strengths

• Simulation is based on a detailed one-minute resolution yearly mission profile for a specific location (Narsapur, India).
• Includes a substantial Monte Carlo simulation with 10,000 samples to model parameter variation.
• Provides a direct performance comparison across four semiconductor technologies (IGBT, SJ-M, SiC-M, GaN-H).
• Results quantify a potential 40% loss reduction for wide-bandgap semiconductors compared to conventional IGBTs.

Limitations

• Dataset is very small (5.5 KB), indicating limited scope, likely containing summary results rather than raw simulation data.
• Row count and detailed column-level documentation are unknown, requiring manual inspection after download.
• Data is simulation-based; its applicability to real-world hardware may require validation.
