Bourns Circuit Conditioning Short Form Brochure

Bourns Circuit Conditioning
Short Form Brochure
Introduction
Power electronics cover different disciplines ranging from
magnetics design, EMI filter design, analog electronics, power
semiconductors, circuit protection, and now recently digital
signal processing. The objective of a power electronics circuit
is to modify energy in the form of voltage and current at
different frequencies, or, in other words, to modify the input
voltage and current conditions. This circuit conditioning short
form brochure provides information on the Bourns® product
portfolio for power electronic applications.
A switch mode power supply and drive can be described as a
series of building blocks as shown in figure 1, each with the
following functions:
A) Protection
a. Protection of the circuit from lightning and switching transients on the AC mains (IEC 61000-4-4 and IEC 61000-4-5)
b. Short Circuit Protection
i. For agency short circuit testing of low power circuits
ii. For prevention of short circuiting of IGBTs on inverter legs
B) EMI a. Conducted emissions (IEC 61000-4-6)
b. Radiated emissions (EN 61000-4-3)
C) Transformer and Output Filter
CUSTOM TRANSFORMER DESIGN EVALUATION WORKSHEET
In order to facilitate the initial feasibility study,
the design engineer should fill out the appropriate
information in the worksheet below. This will allow the
Bourns transformer designer to propose the optimum
design that will achieve the highest possible efficiency.
Bourns has standard cores, bobbins, enamel and single,
double and triple insulated wire in stock for custom
transformer and inductor designs.
