Piezoelectric Transformers and DC-DC Piezo Converters
Piezoelectric transformers are an alternative to wire wound magnetic transformers. They behave differently and have a number of advantages, e.g., they are lighter and smaller, and they have excellent electrical isolation and no magnetic stray flux. For these reasons piezoelectric transformers have been used in applications such as high voltage generators in CCFL backlighting and inverters for laptop computers.
There are two main types of piezoelectric transformers:
- Step-up piezoelectric transformers
- Step-down piezoelectric transformers
Step-up piezoelectric transformers are typically designed using Rosen-type configuration, while Step-down piezoelectric transformers are typically achieved using radial-type Transoner piezoelectric transformers.
The following standard component categories are currently available:
