Digital Power Interleaved PFC Reference Design
High performance power supplies are
used in a wide variety of applications
ranging from telecommunication
equipment, industrial equipment, digital
televisions, lighting, air conditioners and
other home appliances. They all need solutions for power
factor correction to improve overall efficiency, improve the
input power factor, voltage regulation and Total Harmonic
Distortion (THD) of the input current. Digital interleaved
power factor correction methods provide many benefits over
older PFC techniques.
Digital Pure Sine Wave Uninterruptible Power Supply
(UPS) Reference Design
This reference design is based on
the dsPIC33F “GS” series of digital
power DSCs. This reference design
demonstrates how digital power
techniques when applied to UPS
applications enable easy modifications through software,
the use of smaller magnetics, intelligent battery charging,
higher efficiency, compact designs, reduction in audible
and electrical noise via a purer sine-wave output, USB
communication and low-cost overall bill-of-materials.
Digital LED Lighting Development Kit
This LED lighting development kit
enables designers to quickly leverage
the capabilities and performance of the
dsPIC33 ‘GS’ DSCs and this reference
design to create a 100% digitally controlled
ballast function, while including advanced
features such as dimming and color hue control. The
dsPIC33 ‘GS’ devices can support an entire system
implementation for LED lighting products, including power-
conversion circuits, such as AC-to-DC and DC-to-DC
conversion, along with functions such as Power Factor
Correction (PFC), which are necessary for a complete
product and lower overall system cost.
Grid Connected Solar Micro Inverter Reference Design
This reference design demonstrates
the flexibility and power of SMPS DSCs
in grid connected power conversion
systems. This reference design works
with any PV panel of maximum of 220W
having open circuit voltage between 25V to 55V DC. This
reference design will ensure maximum power tracking for PV
panel voltage between 25V to 45V DC. Two versions of this
reference design are available to support 110V and 220V
grid.
Additional information for all reference designs is
available at www.microchip.com/power.
AC/DC Reference Design
This design is a completely digitally
controlled full-featured 300W (5V/23A
and 3.3V/69A) power supply with active
PFC. The design offers a universal AC
input with active power factor correction
followed by two stages of DC/DC power
conversion. The first stage converts the high-voltage DC
link to a 12V DC bus via a zero voltage transition full-bridge
converter incorporating secondary side synchronous
rectification. The second stage consists of single-phase and
multi-phase buck converters.
Buck/Boost Converter PICtail Plus Card (AC164133)
A low-cost development platform for
dsPIC33FGS SMPS devices, the buck/
boost converter PICtail Plus card has
two buck stage outputs and one boost
stage output. The buck/boost converter
operates from an input supply of +9V
to + 15V DC. Various performance measures like digital
control loop performance of power conversion, dynamic
load performance, multi-phase buck and synchronous
buck converter operation, parallel operation of two buck
converters and multiple output control with a single dsPIC
device can be evaluated for dsPIC33FGS SMPS solutions.
This board can be used with either the Explorer 16 board or
the 16-bit 28-pin starter board and the dsPIC33F SMPS and
digital power conversion devices.
Quarter Brick DC/DC Converter Reference Design
This reference design provides an easy
method to evaluate the power, and
features of SMPS DSCs in high density
quarter brick DC-DC converters for
Intermediate Bus Architectures (IBA). This
reference design is implemented using a single dsPIC33F
“GS” digital power DSC from Microchip that provides the
full digital control of the power conversion and system
management functions.
DC/DC LLC Resonant Converter Reference Design
This reference design operates over a
wide input voltage range (350-420V DC)
with a nominal input of 400V, providing
a 12V DC output, while maintaining
high-voltage isolation between the
primary and secondary. This reference
design is implemented using a single dsPIC33F “GS” digital
power DSCs from Microchip that provides the full digital
control of the power conversion and system management
functions.
