Safe and Reliable Automotive Electronics
We are developing new design and test practices for automotive electronics to ensure the reliability of the vehicle and the safety of its occupants.
Performance-Based EMC Design of Electronic Systems
Developing new design models and practices to ensure that electronic systems meet all EMC requirements before they are built and tested. This allows design decisions to be made based on the actual requirements, and eliminates some of the uncertainties associated with design trade-offs that impact electromagnetic compatibility.
Efficient, Low-Noise Motor Drivers and Power Inverters
CVEL researchers are developing methods for reducing the electrical noise and
improving the efficiency of DC-DC power converters
and motor drivers for AC and brushless-DC motors.
Failure-Mode Models for MLCC and Tantalum Capacitors
Evaluating the gradual deterioration of MLCC and tantalum capacitors that can occur due to exposure to medium-to-high voltage transients; and developing models that represent the electrical behavior of these components.
Improved Tire Pressure Monitoring
Developing a better way to transmit and receive RF signals in cars and trucks to conserve power and improve communication.
Efficient Capacitor Charging
CVEL researchers are developing a technique for charging ultracapacitors that could
greatly improve the efficiency of automotive systems that rely on ultracapacitors for energy storage.
Automotive EMC Expert
System
CVEL researchers are developing expert
system algorithms to diagnose and solve
electromagnetic compatibility problems
with automotive designs before the
first prototypes are built.
EMC Expert System for Printed Circuit
Board Layout
These expert system algorithms work
with board layout tools to identify
electromagnetic compatibility problems
with a circuit board design before it
is built.
EM Modeling Using SPICE Circuit Solvers
Researchers at Clemson University are combining Finite Element electromagnetic analysis techniques with SPICE circuit solvers to perform fast and accurate electromagnetic simulations.
Evaluating ICs as Sources of Radiated Emissions
CVEL Researchers developed test procedures for characterizing integrated circuits in a
manner that quantifies their ability to generate radiated electromagnetic emissions when mounted
on a circuit board and placed in a complex system.
Electronic Device

CVEL researchers have developed
techniques to automatically detect and
identify electronic devices based on
their unintentional electromagnetic

CVEL researchers investigated
methods for reducing the unintentional
emissions from complex semi-conductor
devices such as microprocessors,
microcontrollers, and large
field-programmable gate arrays.
Reducing AM Radio Interference in a Tractor
CVEL researchers analyzed the coupling paths
that allow electronic noise to be heard in
AM radio systems installed in high-tech tractors.
