Addict Technologies as developed
two different configuration modules for the
PCIRIO card to provide PWM
capabilities. A tiny version
which generates two PWM signals
and a full version for generating up to six PWM signals. These signals can be used to control a 3-phase bridge producing a variable voltage and frequency source to power an AC motor. Such signals can also control DC motor speed.
Tiny PWM
module for PCIRIO card:
This module has been
designed to be used on PCIRIO
card populated with Xillinx
XCS05 FPGAs. It is a truncated
version of the full PWM module
to fit in smaller FPGAs. It has the following
specifications:
Specifications:
- One PWM
output "Low side":
AL
- One PWM
output "High
side": AH
- One input
to enable/disable both PWM
outputs
- One input
to change outputs polarity.
(Active high or low)
- One output synchronized
on the PWM period
- One 6-bits
input port and one 8-bits
output port.
- 12-bits
resolution on PWM frequency
- Output
frequency from 2034.51Hz to
8.333MHz in 120ns increment.
- 12-bits
resolution on PWM duty-cycle
- Dead time
adjustable from 0ns to
15.3us in 60ns increment.
(8-bits)
Full
PWM module for PCIRIO card
This module as been designed to
be used with PCIRIO card
populated with Xillinx XCS30
FPGAs. It mimics most of the
functionalities of the ADMC300
integrated chip by generating three pairs of complemented and
dead-time-adjusted center-based
PWM signals.
Specifications:
- Three PWM
outputs "Low
side": AL, BL, CL
- Three PWM
outputs "High
side": AH, BH, CH
- One input
to enable/disable all PWM
outputs
- One input
to change outputs polarity.
(Active high or low)
- One output synchronized
on the PWM period
- 16-bits
resolution on PWM frequency
- Output
frequency from 126Hz to
8.25MHz in 121.2ns
increment.
- 16-bits
resolution on PWM
duty-cycle, independent for
each phase.
- Dead time
adjustable from 60.6ns to
15.4us in 60.6ns increment.
