Piezo Drivers - Advanced Piezo Drivers enable robust high performance control over both Piezo and other reactive transducers and devices.
QorTek has established several highly equipped Technology Center Labs within its operation. These Labs encompass nearly every aspect of product design and engineering through to comprehensive product test evaluations.
QorTek has a completely equipped laboratory for piezoelectric device characterization and piezo-mechanical system testing. Originally set-up to investigate its funded development of high power density piezoelectric transformer technology and microelectronics security systems, the lab has now been extended to enable a wide range of piezoelectric device related testing as to include comprehensive automated thermal characterization, mechanical loading (stress-strain vs. applied voltage/power), displacement (down to nm range) and electromechanical coupling. QorTek’s piezo-mechanical lab also includes capability for piezoelectric device characterization including D33 measurement, high accuracy laser-micrometer based displacement measurements, as well as electrical impedance, capacitance, loss, Q, and general electrical network analysis capabilities via both an HP E4980A and HP4395A.
QorTek maintains a wide array of state of the art hardware and software tools for the development of digital and microelectronic systems; these include Xilinx ISE Design Suite, a range of software and electronics systems including in-circuit emulators, debuggers, download/programming hardware, EVM boards, DSK tools and device simulators. To complement the digital hardware design tools, QorTek is registered with both Microsoft MSDN and National Instruments Developers Suite PC software design tools. This allows QorTek to develop PC graphical user interface tools (C/C++/C#, Visual Basic, LabWindows/CVI, LabVIEW) for its own digital control hardware. It has developed a number of proprietary LabVIEW and MATLAB engines; software and TI DSP or Cygnal Microcontroller interfaces for matrix interconnect electronics design, visualization and control logic algorithms.
Analog/Mixed Signal Electronics Design & Simulation Lab:
QorTek has established a complete suite of professional schematic capture, 3D PCB layout and analysis tools for electronics design and simulation including Altium EDA, Intusoft ICAP/4 and Cadence OrCAD systems. QorTek maintains extensive equipment and facilities in their power electronics laboratory that include high voltage/current power supplies, variacs, curve tracers, LCR meters, isolation transformers, pulse generators, signal generators, and digital oscilloscopes with the latest measuring software from Tektronix (power analysis, fast acquisition, DPOJET). The high power electronics lab is also equipped with high voltage differential measurement probes (up to 5200Vrms) and current probes with measurement capability to 150 A. QorTek maintains a range of modern DC and AC power analysis tools including an Agilent N6705A DC Power analyzer with a range of custom interfaces developed specifically for capacitive load power electronic applications.
Materials Characterization Lab:
The materials characterization laboratory installation includes Denton DV-502 vacuum chamber that is capable of 1X10-7 Tor, Despatch 900 Series (25 to 274 Deg-C) environmental bench chamber, thermal chambers with a range of -73°C to +250°C for materials characterization and performance assessment. The lab also includes a temperature/humidity chamber with a range of -68°C to 175°C and humidity range of 10% to 95% RH and a Thermolyne 6000 Furnace with a maximum temperature of 1200°C for materials characterization and performance assessment.. The lab also possesses a shock and vibration system that can test a various devices with 75 pounds of force in all three axes. Additionally, the lab includes a custom Keithley electrometer system with custom probes to enable automated pressure gradient/temperature gradient response data logging and a FLIR thermal imaging camera to detect thermal anomalies in designs and components. All of QorTek's laboratories include DPO7000 Series Digital Phosphor Oscilloscopes and DPO3000 Mixed Signal Oscilloscope and the latest software to perform precise small signal measurements. Additional materials characterization capabilities include a range of load cells, strain gauges, accelerometers, shaker tables, and their respective amplifiers, control and data acquisition systems. QorTek also maintains an HP4395A and E4980A for dielectric, and reactive component and material characterization.
FEA Modeling, Simulation & Prognostics Lab:
QorTek’s Modeling, Simulation and Prognostics Lab has the latest solids modeling software SOLIDWORKS®, Finite Element Analysis software COMSOL Multiphysics®, MATLAB and SIMULINK in addition to CUDA/C tools for parallel processing. Specific FEA modeling tools include comprehensive structural mechanics analysis, thermal structure interaction, AC/DC and electromagnetic modeling as well as extensive piezoelectric device modeling capability. Within the Software Laboratory environment QorTek has custom developed tools interactive multiport solvers that provide cutting edge simulation that takes into account interactive action between electrical, mechanical, and thermal parameters. QorTek also has developed a compact high powerful computing platform based on the Mini ITX Motherboard specific for GPU computing. The PC is equipped with an Intel Core I7 3.5GHz Quad Core Processor, 16G of RAM and a GTX670 GeForce GTX graphics card. A dedicated ThinkPad for the lab has an Intel Core i7 2.9GHz processor, 32G of RAM, and a GT630M GeForce graphics card utilized for GPU MATLAB data intense programming. Numerous Xilinx Virtex development boards are also available for prototyping and testing algorithms. QorTek currently has two Virtex 7 based boards, VC707 and the VC709, and the ML605 Virtex 6 based development board. QorTek also has 20T of in house storage for handling large file storage.
