| Abstract | |
Piezoelectric transformers are devices able to raise an electrical input voltage with low energy losses. However, there are a few reports on the designing of multiferroic piezoelectric transformers. In this paper, an alternative bi-layer radial mode piezoelectric/magnetoelectric transformer approach by using a Nb doped (1wt%) Pb(Zr)(53)Ti47O3 piezoelectric ceramic as actuator, and a La doped (5wt%) (0.6)BiFeO3-(0.4)PbTiO3 magnetoelectric ceramic as transducer has been tested. The voltage gain and the efficiency were determined as a function of the frequency and the load test resistance. A typical response, characteristic of bi-layered radial mode solid-state transformer, with a voltage gain of 2.5 at a load resistance of 7k, and an efficiency of 0.15 at load resistance 1k, were obtained. The results showed the feasibility of such multiferroic transformer for some practical smart and multifunctional devices applications. (AU) | |
