Microchip Makes it Easier to Design an On-Board Charger Solution
10 June 2024 - 10:00PM
The market for Battery Electric Vehicles (BEVs) and Plug-in Hybrid
Electric Vehicles (PHEVs) continues to grow as the push towards
decarbonization requires sustainable solutions to reduce emissions.
A critical application for EVs is the on-board charger, which
converts AC power into DC power to recharge the vehicle’s
high-voltage battery. Microchip Technology
(Nasdaq:
MCHP) today announces an
On-Board Charger (OBC)
solution that uses a selection of its automotive-qualified
digital, analog, connectivity and power devices, including the
dsPIC33C Digital Signal Controller (DSC), the MCP14C1 isolated SiC
gate driver and mSiC™ MOSFETs in an industry-standard D2PAK-7L XL
package.
This solution is designed to increase an OBC system’s efficiency
and reliability by leveraging the dsPIC33 DSC’s advanced control
functions, the MCP14C1 gate driver’s high-voltage reinforced
isolation with robust noise immunity and the mSiC MOSFETs’ reduced
switching losses and improved thermal management capabilities. To
further simplify the supply chain for customers, Microchip provides
the key technologies that support the other functions of an OBC,
including communication interfaces, security, sensors, memory and
timing.
To accelerate system development and testing, Microchip offers a
flexible programmable solution with ready-to-use software modules
for Power Factor Correction (PFC), DC-DC conversion, communication
and diagnostic algorithms. The software modules in the dsPIC33 DSC
are designed to optimize performance, efficiency and reliability,
while offering flexibility for customization and adaptation to
specific OEM requirements.
“Microchip established an E-Mobility megatrend team with
dedicated resources to support this growing market, so in addition
to providing the control, gate drive and power stage for an OBC, we
can also provide customers with connectivity, timing, sensors,
memory and security solutions,” said Joe Thomsen, corporate vice
president of Microchip’s digital signal controller business unit.
“As a leading supplier to OEMs and Tier-1s, Microchip offers
comprehensive solutions to streamline the development process,
including automotive-qualified products, reference designs,
software and global technical support.”
Here is an overview of the key components in this OBC
solution:
- The dsPIC33C DSC is AEC-Q100 qualified and features a
high-performance DSP core, high-resolution Pulse-Width Modulation
(PWM) modules and high-speed Analog-to-Digital Converters (ADCs),
making it optimal for power conversion applications. It is
functional safety ready and supports the AUTOSAR®
ecosystem.
- The MCP14C1 isolated SiC gate driver is AEC-Q100 qualified and
is offered in SOIC-8 wide-body package supporting reinforced
isolation and SOIC-8 narrow-body supporting basic isolation.
Compatible with the dsPIC33 DSC, the MCP14C1 is optimized to drive
mSiC MOSFETs via Undervoltage Lockout (UVLO) for VGS = 18V gate
drive split output terminals, which simplifies implementation and
eliminates the need for an external diode. Galvanic isolation is
achieved by leveraging capacitive isolation technology, which
results in robust noise immunity and high Common-Mode Transient
Immunity (CMTI).
- The mSiC MOSFET in an AEC-Q101-qualified D2PAK-7L XL surface
mount package includes five parallel source sense leads to reduce
switching losses, increase current capability and decrease
inductance. This device supports 400V and 800V battery
voltages.
Microchip has published a white paper that
provides more information about how this OBC solution can optimize
a design’s performance and speed up its time to market.
