Electric power

Modelling a redefined architecture for concentrated photovoltaic power plant

The whole research projects that concern the concentrated photovoitaic (CPV) are systematically about the yield improvement of the cell. The positioning of the work presented here is at the cell interconnections for achieving a stable DC bus to…

Traveling wave piezoelectric transformer for multi-level insulated gate-driver power supply

The traveling-wave piezoelectric transformer (TWPT) is a new topology of piezoelectric transformer providing a multi-phases system of voltages at its output. The inherent galvanic insulation of piezoelectric transformers makes them particularly…

Dual control on structure and magnetic properties of Mg ferrite: Role of swift heavy ion irradiation

Effect of swift heavy ion irradiation on MgFe2O4 (annealed at 450 °C/3 h) sample prepared by a sol–gel auto-combustion procedure has been studied. Single phase samples were irradiated with 120 MeV 28Si9+ with ion fluence: 1 × 1011, 1 × 1012, and 1 ×…

Synthesis, structural and magnetic properties of cadmium substituted Li-ferrite

We present study of Li 0.5-x/2 Cd x Fe 2.5-x/2 O 4 (thermally treated at 450 °C for 3 hours) nano crystalline ferrites, synthesized by sol-gel auto-combustion method. X-ray diffraction (XRD), magnetic measurements were used to probe the structural,…
