It was found that thermopower of BiTeI can be enhanced with small amounts of CuI additions, while both thermal conductivity and electrical conductivity decrease in polycrystalline samples26,33. The TE figure of merit nevertheless deteriorates as compared with the undoped single crystals. It was ...
An additional issue can be considered: situations when a train is in braking/regenerative mode and some amount of active power is injected into the catenary [4,5]. As known, overload conditions are not particularly appreciated and should be avoided as much as possible; they give origin to ...
Not a priori knowing the amount of detuning required in the design to limit the open secondary surge current on primary coil, a practical initial estimate for the transferred power of the circuit is obtainable considering an average value λ for λ = sin(ϕ1 − ϕ2). That can be ...
