Universal DSP Controller

Universal DSP Control Board

PCTI’s Universal DSP Controller may be the only control board that you’ll ever need. This revolutionary control solution provides easily customizable control solutions for any power electronic product via software modification. It has a wide variety of applications within power conversion equipment including power supplies, UPS’s and motor drives. PCTI began research on DSPs for industrial applications in 1994 and successfully implemented them into end-use production in 1998. The DSPs presently used are the Analog Devices ADMC401 as well as the Texas Instruments TMS 2808. Research has also been conducted on the Analog Devices 21000 line of DSPs. We are now migrating to our sixth generation of DSP control with Texas Instrument’s TMS320F28M36, which combines C2000 floating point DSP and Cortex M3 ARM in one single chip. Floating point DSPs enable more advanced control algorithms, while M3 ARM can implement control panel and remote communications for our machines.

Why Use DSPs?

The innovation of DSP control into power electronic designs is an excellent example of the advantages provided by major technological advances. By replacing classic control with DSP control, the primary advantages are achieved by replacing hardware with flexible software. The advantages are even more dramatic because they don’t just extend to reducing cost and increasing performance over classic designs. They can extend to many corners of the organization and include overall staff reductions and the advantages that standardization of designs across product lines bring, depending on the company. Following are the potential benefits for your organization.

  1. Lower Cost. The controller will reduce the material cost of the customer’s equipment, labor content, and overhead related to both materials and labor (purchasing transactions cost, accounting transactions costs, factory overhead). This reduction may be from 20% to 50% of the cost of the unit depending on the equipment power rating.
  2. Reduction in the size and weight of the unit. As with calculators in the early 1970’s, technological advancement allows equipment to become smaller and lighter. Smaller and lighter can translate into several cost reductions including labor, transportation, and materials.
  3. Increased performance. The fast math-intensive functions and high execution speed allow for faster control response and correction to achieve desired parameters and therefore a better performing machine.
  4. Automation of in-house testing. The DSP software allows for automation of the testing process, thus reducing the labor content of the technical staff.
  5. Increased design flexibility. The software within the DSP can be easily modified to optimize the application once in use in the field or if the application changes once the unit is installed. This also makes tweaking the design easy in-house.
  6. An increase in application flexibility. The application that the equipment  addresses can be easily modified via software changes as opposed to design changes.
  7. Ease of design modification or troubleshooting in the field. Customers wanting to diagnose or modify the functionality of their equipment once they receive it can have it done via software and modem rather than returning it to the factory or having an expensive service call.
  8. A reduction in energy consumption. Active harmonic cancellation and better energy management achieved by the real-time control of the DSP and the software that controls it reduces energy consumption.
  9. Standardization across product lines. The same controller board can be used for a battery charger, an inverter or a switched mode power supplies; thus economics are achieved by reducing the number of components in inventory across numerous product lines as well as the overhead associated with specifying and purchasing components.
  10. Reduced Time to market. Software is certainly easier to revise than manufactured hardware.

The advantage to using PCTI for your DSP needs is because we know your power conversion applications and have experience implementing DSPs into end-use equipment.
