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,…
