B.S.I.: The British Standards Institution is an
organization that develops standards and tests
products/systems for compliance. Associated
with B.S.I., Technical Help to
Exporters (T.H.E.) provides
reference material on world
wide standards.
Brownout: A reduction or sag in the ac line or
system power bus. If not protected against sags
(by an adequate hold-up time or extended input
ranges), an ac input power system could inadvertently
shutdown.
Brownout Rated: An ac input power supply that
has been designed to operate within specifi ed
limits in the event of a brownout (sag) in the input
ac mains or system power bus.
Brute Force Supply: Basic power supply that
provides an unfi ltered/unregulated output.
Buck Regulator: A basic switching converter
topology (see Figure 3) that uses a series switch
(Q1) to chop the input voltage. The resulting pulses
are applied to an averaging LC fi lter. (L1,C1). Buck
regulators will only produce an output voltage lower
than the input voltage level. See Boost Regulator,
Bridge Converter, Flyback Converter, Forward
Converter, Push-Pull Converter and Resonant
Converter.
