00:00:03.698 --> 00:00:04.604
Hello.

00:00:04.604 --> 00:00:09.468
We’re looking at Isolators for on-board
charging systems.

00:00:09.468 --> 00:00:14.625
I’m Steve Schablitsky,
a high-voltage test engineer at NVE Corporation.

00:00:14.625 --> 00:00:17.420
NVE is a leader in practical spintronics.

00:00:17.420 --> 00:00:20.424
We invented the first nonoptical isolators
in 2000, 

00:00:20.424 --> 00:00:22.910
and we’re still leaders in isolator technology.

00:00:23.515 --> 00:00:26.306
IL700 isolators are ideal for On-board Charging

00:00:26.306 --> 00:00:29.900
and similar applications that require isolation before a gate driver.

00:00:30.340 --> 00:00:34.370
The key advantages of our isolators in this
type of application compared to optocouplers

00:00:34.370 --> 00:00:36.584
or other isolators include:

00:00:37.024 --> 00:00:41.400
Best-in-Class 100 kV/microsecond Common Mode Transient Immunity.

00:00:41.400 --> 00:00:44.740
Silicon Carbide MOSFETs can switch high voltages
very quickly,

00:00:44.740 --> 00:00:48.903
which improves efficiency
but generates very fast voltage slopes.

00:00:48.903 --> 00:00:51.079
High CMTI means
the isolators can support the speed

00:00:51.079 --> 00:00:53.343
without spurious switching.

00:00:54.155 --> 00:00:57.673
The V-Series versions
have best-in-class six kilovolt isolation

00:00:57.673 --> 00:00:59.644
to protect electronic control circuitry

00:00:59.644 --> 00:01:01.898
well beyond the minimum level of existing standards.

00:01:02.439 --> 00:01:05.082
The propagation delay is short,
and it’s matched between channels

00:01:05.082 --> 00:01:07.600
within a device,
and to within just 3 nanoseconds

00:01:07.600 --> 00:01:09.560
between different devices.

00:01:09.560 --> 00:01:11.799
That means the isolators support
high-speed switching

00:01:11.799 --> 00:01:14.519
with minimal waveform distortion.

00:01:14.857 --> 00:01:17.953
Our unique polymer-ceramic
composite isolation barrier

00:01:17.953 --> 00:01:20.637
provides more than 44000 years barrier life--

00:01:20.637 --> 00:01:23.290
far in excess of the 30-year agency-mandated minimum.

00:01:23.730 --> 00:01:25.718
This means the ultimate in reliability 

00:01:25.718 --> 00:01:28.885
in critical applications like OBC.

00:01:30.137 --> 00:01:33.035
NVE isolators were recently selected
for the BeFast© on-board charging platform

00:01:33.035 --> 00:01:37.045
by Pewatron, a member of the Angst+Pfister Group.

00:01:37.790 --> 00:01:40.200
The two-direction IL721
is a perfect match 

00:01:40.200 --> 00:01:43.504
driving the IXYS non-isolated Gate Driver,

00:01:43.504 --> 00:01:45.839
allowing the driver to run at its maximum speed, 

00:01:45.839 --> 00:01:49.077
without being limited by the low CMTI of optocouplers.

00:01:50.536 --> 00:01:52.452
…and NVE offers a full line of channel configurations

00:01:52.452 --> 00:01:56.608
in the IL700 / IL200 isolator product family. 

00:01:56.946 --> 00:02:01.696
Here are links to more information on the
isolators and the OBC Evaluation Board:

00:02:02.000 --> 00:02:04.068
There are other videos showing details of how we test for 

00:02:04.068 --> 00:02:06.000
best-in-class isolation voltage… 

00:02:06.203 --> 00:02:09.267
and best-in-class Common-Mode Transient Immunity.
