High Output Voltage Dc/Dc Converter Based On Parallel Connection Of Piezoelectric Transformers

In recent years, Piezoelectric Transformer (PT) has attracted attention in many practical applications in power electronics field. But the fact that, PT still has some drawbacks and the most issue is the limitation of transferred power. The parallel connection of PTs is introduced in this paper as a solution to the problem that mentioned above. In the experiment part, a high output voltage DOM converter based on parallel connection of two market-available Rosen-type PTs are built in order to verify the capable of improving the output power of PT in parallel operating.
