Keysight Technologies Enables Designers to Save Time and Cost of Iterative Build
and Test of Physical Prototypes
Santa Rosa, California, March 16, 2020 --
Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that helps
enterprises, service providers and governments accelerate innovation to connect
and secure the world, today announced a new add-on to
PathWave Advanced Design System (ADS) that enables designers to perform pre-compliance
testing on virtual prototypes of switched-mode power supply (SMPS) designs. This
new capability saves the time and cost of iterative build and test of physical prototypes.
Demand for SMPS is driven by the need for greater efficiency, increased power
density and lower cost. Fast, low-loss switches made from silicon carbide (SiC)
and gallium nitride (GaN) will power future applications due to the high performance
and efficiency they enable. However, there are unwanted side effects from the high
current slew rate, such as difficultly meeting the radiated electromagnetic interference
(EMI) spec. Pre-compliance analysis of a "virtual prototype" is ideal for managing
this challenge, but until now it required expertise with a complicated, general-purpose
electromagnetic (EM) field solver.
To address this growing need, Keysight has added a radiated EMI capability to
the company's
Power Electronics Professional (PEPro) software, available as an add-on to PathWave
ADS. This new capability includes automatic setup, eliminating the need for an expert,
as well as pre-built test benches, frequency-domain far-field analyses that mimic
real-world tests, and comparison with government-mandated masks.
"High current slew rate in the switched loop brings many benefits but also requires
greater discipline in circuit design and layout," said Dr. Rakesh Lal, Principal
Scientist at Transphorm, a global
semiconductor company leading the GaN Revolution. "The high frequency switching
harmonics give unwanted radiation into the VHF frequency band, so we look to Keysight
for their experience in modeling these effects. PEPro encapsulates their decades
of experience and makes it accessible to power electronics designers to optimize
wide bandgap circuits and layouts for highest performance and reliability."
"The interactions between PE, SI, PI and EMI are well known. Being able to simulate
all four together in a single environment adds tremendous visibility to the design
process," said Steve Sandler, Managing Director of
Picotest, a company that specializes in
high fidelity testing and measurement tools, primarily for power-related applications.
"I talk with dozens of SMPS engineers every year and the one thing they are all
struggling with is EMI compliance in the high di/dt area," said Colin Warwick, product
manager for power electronics EDA tools at Keysight. "They really see the value
of the pre-compliance ‘virtual prototyping' capability of this new version of PEPro."
