| DSP TECHNOLOGY |
 |
The primary reason for
using a DSP instead of a traditional microprocessor is speed,
the ability to move samples into the device, carry out the
needed mathematical operations, and output the processed data.
|
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 you, the customer.
|
 |
|
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. |
|
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. |
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. |
Automation
of in-house testing . The DSP software allows
for automation of the testing process, thus reducing
the labor content of the technical staff. |
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. |
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.
|
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. |
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
|
Reduced
Time to market . Software is certainly easier
to revise than manufactured hardware.
