Precision Voltage & Current Controller

PCI has a broad set of competencies important to a wide range of voltage or current control applications. If your application is unique and challenging, PCI can help, often when others can not or will not. PCI is your most experienced supplier when power, precision, or bandwidth are difficult to achieve; when your "load" begins to look like a short circuit or an open circuit and your existing solutions fall short of requirements. Here is a partial list of applications.

  • Linear motor or DC brush and brushless motor drives (particularly if available power, bandwidth, or fidelity are challenging)
  • High speed spindle motors
  • Motors having more than 3 phases (multiphase), or requiring flux vector control. Example: Magnetic self-bearing (passive bearing) motors and low inertia motors or very high speed motors where maximum torque over a wide speed range is important
  • Applications requiring fast and precise high voltage or current slew rates. The MRI gradient amplifier is one example
  • Extremely fine and repeatable positioning or velocity control as with celestial tracking associated with telescopes and observatories
  • Exceptionally low torque ripple for precise torque control or positioning applications like photo-lithography or optical scanners
  • High bandwidth output for voice coil actuators or electromechanical vibration systems
  • Management of electro-magnetic fields. MRI shim amplifiers would be one example; particle accelerators and particle beam focusing systems are another
  • Active or passive magnetic bearings and levitation systems
  • Multi-axis or multi-channel versions of any of the above
