A Novel Non-Isolated High-Gain Non-Inverting Interleaved DC–DC Converter
High-gain DC–DC converters are being drastically utilized in renewable energy generation systems, such as photovoltaic (PV) and fuel cells (FC). Renewable energy sources (RES) persist with low-level output voltage; therefore, high-gain DC–DC converters ...

Theoretical study about the gain in indirect bandgap semiconductor optical cavities [PDF]
Indirect bandgap semiconductors such as silicon are not efficient light emitters because a phonon with a high momentum is required to transfer an electron from the conduction to the valence band. In a recent study [M. J.
