DC/DC Piezoelectric Converters products

Piezoelectric transformers combine both the direct and the converse piezoelectric effects.  Basically, a piezoelectric converter consists of an input section and an output section.  When the input section is driven by an AC input voltage, a vibration is established in the ceramic body due to the direct piezoelectric effect.  This vibration is extended to the output section whin in turns generates an output voltage. 

If the piezoelectric converter is driven in the neighborhood of its resonance frequency, very efficient electrical to electrical conversion is achieved.  Through specific design of the input and output section, piezoelectrical transformers can be designed for step-up or step-down transformation with efficiencies higher than 95%.

Piezoelectric converters do not require winding electrodes and all the entire ceramic material is used in the acoustic transfer, thus providing a higher power density than magnetic transformers.  Consequently, weight and size is greatly reduced.  Furthermore, piezoelectric materials are made of non-magnetic materials with the significant benefit for applications sensitive to EMI radiation. 

This is the core technology used in Micromechatronics Inc's new DC/DC piezoelectric-based high voltage converters.  The new DC/DC converters include all the driving electronic components as well as the output voltage rectifying parts to achieve a widely input voltage and output load regulated units. 

Micromechatronics, Inc now manufactures the world's first high voltage piezoelectric converter product line.  We have three DC/DC Converters:  2kVdc/4W; 5kVdc/5W; 10kVdc/5W.  The converters operate at an input voltage of 8 to 14 Vdc.  They are fully regulated against changed of the input voltage and the output load, which can be programmed from 0 to 100%.  This is done through control pin from 0 to 2.1 V.

The use of non-magnetic technology to achieve the high voltage generation, make them ideal for medical, military and space applications where magnetic signature could jeopardize the application reliability. 

Other applications include pulse generators, ignition systems, laser power supplies, night vision devices, spectrometers, and traveling wave tubes.
