Piezoelectric Converters for DC/DC and AC/DC applications
نویسنده
چکیده
This paper introduces a cutting-edge transformer technology – the piezoelectric transformer – currently considered as a potential candidate to replace magnetic transformers in resonant switching converters. Magnetic transformers are extensively used for providing step-up and step-down voltages while allowing input to output isolation in ac-dc and dc-dc converters. Even with the extensive use, this component is still the largest, heaviest, and magnetically noisiest component in the power conversion chain. The paper introduces the reader in the piezoelectric transformer technology and proposes a simplified dc/dc converter case scenario to illustrate the different steps involved in applying this technology.
