POLYDRIVE® High Voltage Amplifier

The 50 Watt POLYDRIVE® power amplifier is an economical choice for driving a wide range of loads. With its small size and innovative Advanced Power Technology™, this amplifier requires less bench space than comparable products while producing the same level of output power. Ideally tailored for applications where portability is important, the POLYDRIVE® PZT Driver is especially convenient for offsite work locations. 

A variety of built-in features are included to safely and efficiently drive highly reactive loads from DC – 50 kHz. With a maximum output voltage capability of 500 Vp-p,  this bi-directional regenerative amplifier is capable of recovering unused energy delivered to the load during one cycle and recycling that energy for use during the next cycle. This allows for efficient, high-peak drive current output with minimized power input to drive reactive loads. Due to the high efficiency performance and small form factor, the POLYDRIVE™ is the ideal solution to transition from design phase testing to an integrated system solution in the final OEM application.

  • “QorTek has provided innovative products that have powered our underwater acoustic transducers, allowing us to support the US Navy with much needed systems. QorTek has been especially outstanding in backing up their products with excellent support, not only with phone support but their physical presence during key phases of our lab and field testing. We view this as being above and beyond the normal level of support provided by subsystem suppliers.”

    Peter Ulrich, Principle Investigator, Navmar Applied Sciences Corporation
  • QorTek’s knowledgeable engineering staff worked closely with our engineers in understanding our needs to provide us with the customized high power amplification and complex algorithm control that allowed us to move our product to the next level. Working with QorTek was a great experience and their products reflect their commitment to excellence.

    Maureen L. Mulvihill, PhD, President and CEO, Actuated Medical, Inc.
  • QorTek is a very agile and innovative group. They have a broad set of skills and talents. I have engaged them on several design and development projects and they have delivered on each one. They not only delivered the desired system, but they also educated us immensely on the new technology we were adopting. I have no hesitation in going to them in the future for any power or control design needs.

    Douglas Memering, Director - Product Planning Fuel Systems, Cummins, Inc.
  • I have had the pleasure of working with QorTek and its technologists for nearly 15 years, on many different projects, ranging from flutter test surfaces for NASA to guided hard-launched munitions for DARPA. The engineering solutions were always lower in weight and volume than expected and contracted with superior performance. Basically, QorTek is our go-to company for piezoelectric actuation and driving electronics.

    Dr. Ron Barrett, President and O.E.O., Barrett Aerospace Technologies
  • APC International has been working with QorTek for several, years on various engineering projects. QorTek's experience, knowledge and expertise working with piezo devices and drive electronics has been invaluable. QorTek's personal have always been very helpful and attentive throughout the entire process. APC looks forward to working with QorTek for many years to come.

  • QorTek provided the critical skills necessary to help us complete our Phase I and II SBIR project. Without their assistance with power amplifier design and architecture the program would not have been nearly as successful. The technology they developed may have other applications within our company that we are excitedly exploring.

    Eric Summers, Vice President & Chief Scientist, ETREMA Products, Inc.
  • QorTek is an outstanding partner that we have worked with on several advanced technology projects. They are one of our core small business relationships for the SBIR/STTR Program. We hope to leverage their advanced technology in our programs for mutual benefit.

    Jon Bell, Manager – MST Newport Operations, Lockheed Martin
  • It has been a pleasure to team with QorTek on R&D contracts. We worked with them to successfully develop a ceramic based DC-DC converter and were able to integrate Space Micro's expertise with their advanced electronics as to create a path to space grade components.

    David Strobel, President and CEO, Space Micro, Inc.
  • "The QorTek team has deep technical understanding of a wide variety of projects. It is stimulating to work with such a talented team of engineers and managers. They were able to connect the dots from our SiC device solutions to the DoD customer requirements"

    Dr. Ranbir Singh, President/CEO, GeneSiC Semiconductor Inc.
  • “I have collaborated with QorTek, Inc. since its inception. This company is characterized by excellent engineering credentials and skills, experience, professional ethics and knowledge of its engineers, and disciplined and organized management style. Working on numerous projects as a consultant I have always been impressed by the quality of the projects developed by the company and the inventiveness demonstrated in its designs.”
