The
Buck Regulator
In Part 2-1 of our Power Supply Design
Tutorial we’re going to start a deep-dive into the buck converter and
select one very important part, the output inductor. Then, we’ll begin
with the design philosophy for the input capacitors. The output
inductor, or the buck inductor, is the key piece of this and nearly
every other switching regulator…

BsT-Pulse, de factor standard
device, to characterize power magnetic component
Magnetic component design becomes key
for power electronics. Do we need
new soft magnetic material or optimize the existing one for
SiC&GaN design?
Make such question redundant by testing you coil in the way as you
like,
sinusoidal IEC 62044-3 with BsT-Pro or just pulse till 1kV, with
BsT-Pulse,
powerlosstester helps you to separate hay from wheat.

Common
and differential mode noise AC filtering
Within external and internal
power supplies working with 230VAC noise filtering
is mandatory to comply with European and global EMI reduction rules.
When it
comes to filtering through chokes the magnetic material plays a major
role to
comply with that. The webinar will show you which components will help
you to
reduce size and weight while keeping the performance of filtering on
the same
level and you will learn how to choose the right magnetic filter.
