Piezo Drivers - Advanced Piezo Drivers enable robust high performance control over both Piezo and other reactive transducers and devices.
QorTek was founded in 1998 as a developer and manufacturer of piezoelectronics and piezo actuation mechanisms. The company pioneered regenerative circuitry within power supplies enabling recycling of the high amount of return energy experienced on each cycle when driving capacitive or inductive loads – such as all piezoelectric devices. The concept of regenerative power drivers for piezoelectric mechanisms was enthusiastically adopted by the engineering community and became the foundation for the company’s success.
QorTek later launched the development of novel sensor and actuator devices based on piezoelectric materials. They have continued to build upon their preeminent position as the world’s leader in design of piezoelectronics topologies and circuit designs. There have been several ensuing (regenerative) power products including: all-digital drives, hybrid drives, self-tracking drives, and capacitive drive systems.
QorTek has expanded its technology base to begin a decade-long development of Intelliplastics® sensors and energy harvesting mechanisms. The interest in development of leading edge compact and subcompact power supplies for piezoelectric actuators led QorTek to develop its own mechanical amplified (flextensional) and bimorph actuator technologies. Many of these products are patented.
