Design Challenges
Presently, the vast majority of SMPS are
implemented in an analog fashion. But
analog implementations have significant
disadvantages that can be rectified by
implementing the SMPS using modern
digital mechanisms. Until recently, this
has not been cost effective, due to
performance and cost of the processors
required to do the job. The 56F800 and
56F8300 hybrid controllers specified
here have the required performance,
peripherals, and price targets to enable
SMPS to make the conversion from
analog to digital implementations.
Freescale Semiconductor Solution
The digital 56800/E Switched-Mode
Power Supply minimizes the number of
system components, maximizes the
system reliability, and makes it possible
to easily add advanced functions without
increasing cost.
The performance, integrated peripherals,
and low cost of the 56F800 and 56F8300
controllers specified here make the
digital SMPS possible and practical.
The system in this example is a 100-
Watt SMPS controlled by a 56F801
device on the primary side and a
56F8323 on the secondary side.
Optional components could include user
interfaces, such as an LCD or LED
display.
During normal operation, an AC/DC
rectifier controlled by a 56F801 will
correct the input power factor while
simultaneously rectifying the AC input
voltage. The output of the AC/DC
rectifier is a DC voltage that will feed the
DC/DC converter, which is controlled by
a 56F8323 device. The DC/DC converter
has a full bridge topology, used to
convert the DC Bus voltage to a precise
and constant DC output voltage. For the
Power Factor Correction (PFC)
converter, the 56F801 samples the input
AC voltage, input AC current, and DC
output voltage. The output DC voltage is
regulated by the 56F801, while
maintaining the same phase for both the
AC input current and voltage. The PWM
module on the 56F801 produces the
PWM pulse for the PFC main power
component. The DC/DC converter
controlled by the 56F8323 is operating
on a phase-shifted soft-switching mode,
so that switching losses and noise can
be kept to a minimum.
Control functions implemented within the
primary hybrid controller are:
> Input power factor correction
> Automatic detection of input voltage
frequency
Control functions implemented within the
secondary hybrid controller are:
> Power on/off control
> DC Bus voltage regulation
> Output DC voltage regulation
> DC/DC full-bridge phase-shifted
control strategy
> Power system monitoring and
communication protocols (optional)
> Fault and mode management
