This blog post reports on high voltage DC-DC converters. Today, engineers are sometimes overwhelmed by the choices they face when it comes to selecting a DC-DC converter. These board mounted bricks improve functional efficiency and power density. The bricks come in a variety of sizes, which is both good and bad. We need more sizes, but choosing the right one can be hard! It’s a very technical decision best left to the experts. When looking at DC-DC 12V converters, for example, here are two points to consider:
Output
power. The best DC-DC
converters deliver 66W, leveling up power to
about 450W. In a series, the bricks can
increase power as it moves along the line. Magnetic parts drive improvements
currently, and that’s good news for technology designers.
The bottom line is that one should
check the power rating and the duty cycles (of the load) when choosing a DC-DC
converter. This will help support a wide
operating environment with respect to ambient temperature.
Efficient
operation.
A basic rule of business is to optimize efficiency. The same is true in electronics. DC-DC converters are more efficient when
operating in the full-rated load. The larger
the difference, the more input and output voltage. This yields a less efficient conversion
process, however. Checking efficiency is
important for a variety of reasons (none of which need to be explained to an
expert). Simply check the datasheet to
learn whether power is supposed to be “convection cooled” or “forced air cooled.”
At the end of the day, high voltage DC-DC converters are serious business!
