Power Ring Film CapacitorsTM
SBE UL-recognized Part 700A308911-163
Double the Life or Power of your Inverter!
• Immediately reduce capacitor costs per kW rating
or life requirement – or BOTH!
• Increase life and efficiency of inverter
• Increase reliability and reduce maintenance costs
In today’s most advanced solar energy systems, Power
Ring Film Capacitors™  are the DC link capacitors used
in inverters and other power conversion systems. The
Power Ring Film Capacitor^TM greatly reduces both the
total system cost per kW and component complexity
requirements, while increasing long-term reliability
required in today’s demanding environments of the
power grid. Often, we can achieve a 30 – 40% cost
reduction or a doubling of power and/or lifetime at the
same cost level.
SBE Power Ring Film Capacitors^TM for solar applica-
tions have typical bus voltages ranging from 500 to
1500 Vdc and inverter stage ripple currents ranging
from 100 to 1500 Arms at 2.5 – 7.5 kHz frequencies
(Visitwww.sbelectronics.com/products/specifications/
for details on the individual capacitor elements).
The SBE engineering team can help you with an opti-
mized bank design which can drop in to your existing
space or allow you to create a leading edge new design.
Depending on ripple current, lifetimes range from
100,000 to over 500,000 hours at typical 45 – 60°C
ambient conditions for this market.
SBE can usually provide a “drop in” bank solution to any
existing film capacitor configuration to facilitate field
testing and system evaluation. It also allows for conve-
nient implementation of second sourcing since the “DC
Link bank” is not changed dimensionally – but cost and
performance are improved.
SBE’s approach is to maximize the Power Ring
capability of ripple current per micro-Farad to obtain
the best system power density performance available
in the industry for your component dollar and your
cubic volume of space. In doing so, the DC Link bank is
reduced and more tightly coupled to the IGBT.
SBE has designed multiple options for the DC Link
solution in 500kW rated modules (smaller versions for
200 – 400kW are available).The solutions are modular.
For a leading edge power dense 1MW+ system, simply
combine one or more of these units “end to end”.
A one piece version is also available for any desired
system size.
There are 3 styles of DC Link for Solar, Wind, and
Network Power:
• 700A163 is the most space efficient horizontal
configuration. In order to complete assembly,
this unit ships with capacitors and bus separately.
Because of connections interference, the IGBTs
must be connected to the bus first and the capaci-
tors mounted after.
• 777A103 is a highly space efficient horizontal
design that allows for greater IGBT mounting
flexibility which can be mounted at the customer
site to a fully assembled – integrated DC Link
shipped as one piece.These designs also allow for
a thicker copper connections system at the IGBT
(and typically DC input) for best cost optimization.
• 777A104 is a highly space efficient vertical design
that has the minimal surface area by stacking the
2 x 1500µF capacitors on top of each other with
a thick copper bus for high current density. The
IGBT connections are available for connection at the
customer site to a fully assembled integrated DC Link.
