Gate drivers: more features for the
powerstack “brain”
Gate Driver Unit (GDU) Market for Power Transistors report
LYON, France – November 7, 2014 – The power electronics industry is
still looking for the improvement of power module performance and
reliability. Under this context, industrials pursue the development of its
artificial intelligence by adding new features to the gate driver units
(GDU), considered as the powerstack’s brain.
Yole Développement (Yole) announces its new technology & market
analysis, Gate Drive Unit Market for Power Transistors. Yole’s analysts
propose an overview of the GDU technical challenges and solutions,
dedicated to power electronic applications. They provide a
comprehensive description of the GDU playground. Moreover, the
research market and consulting company offers an in-depth analysis of
GDU technology and cost aspects. Market figures have been also
detailed until 2020.
Industrials develop plenty of circuits, boards, designs and technology
solutions for power electronics applications. Each solution is
dedicated to solving a specific issue. However, the current GDU
market offers no standard solution – only same functions such as:
overvoltage clamping and shape control of the current driver during
turn-OFF – isolation - short-circuit monitoring - VCE FAULT monitoring
Several ongoing improvements are focused on both silicon and
wideband gap materials, especially in using the materials’ entire high-
frequency capability. With such technologies, industrials’ strategy is to
follow powerstacks trends: development of effective switching
solutions, insurance of higher frequency to reduce modules’ size,
“standard” solution identification that could work with different
power module brands …
“This complex market includes captive and open players”, explains Dr
Kamel Madjour, Technology & Market Analyst, Power Electronics at
Yole Développement. “There are several player types that develop
GDUs – pure players, IC makers, power module and inverter makers,
and integrators”, he adds.
Some companies are also proposing improvements in IGBT/MOSFET
performance through their driver technology, based on new design
and software. With new software, some players, mainly pure GDU
players, are developing intelligent monitoring solutions to improve the
… Yole announces a 10%
CAGR for the gate driver
board market between
2013 and 2020. The
market will reach a total
value of ~US$250M by
2020, driven by
renewable energies,
smart-grid
implementation and
automotive applications

maintenance of systems. This is particularly critical for rail and avionics
applications, explains Yole in this GDU market report.
Moreover, according to Yole’s report, no one manufacturer has
differentiated itself via a cutting-edge technology. Indeed, analysts
explain: power module makers and integrators have specific needs,
and want to keep their know-how in-house.
In parallel, same companies can utilize different business models
depending on requirements. Integrators and power module makers
can implement solutions from either external GDU providers or their
customers, depending on specific needs… All results including business
models analysis are presented in Yole’s report.
Under its technology & market analysis, Yole announces a 10% CAGR
for the gate driver board market between 2013 and 2020. “The market
will reach a total value of ~US$250M by 2020, driven by renewable
energies, smart-grid implementation and automotive applications”,
comments Dr Pierric Gueguen, Activity Leader, Power Electronics at
Yole Développement.
The power device market’s recent instability, with a huge growth in
2011, followed by a big drop in 2012, had a strong impact on power
module sales, and consequently on GDUs. Yole’s report evaluates the
potential future growth of the GDU market, which depends on the
following power electronics market trends:
 Significant increase in the automotive sector following Electric
Vehicle (EV) and Hybrid Electric Vehicle (HEV) ramp-up
 Renewable energies and smart-grid implementation driving
industry sector ramp-up
 Steady erosion of the consumer segment, including UPS, due
to price pressure. However, volume (units) will continue
increasing.
Gate Driver Unit Market for Power Transistors report takes into
account GDUs that are only used inside power modules and IPM (i.e.
> 400 volt & >3 amperes).
