Voltage converters intake electrical current at a given supply voltage and shift it to different voltage levels that are appropriate for various forms of equipment. For instance, you’re probably familiar with the power block adapters that transform your local mains voltage into something that your smartphone or computer monitor can use. What you may not know is that this process demands extreme precision. Here’s why engineering tolerances play such a big role in the everyday act of voltage conversion.
Precision Drives Performance Consistency
Modern electronics are far hardier than their predecessors. Such ruggedness doesn’t mean, however, that they can survive reckless abuse.
Your office printer or computer keyboard needs a power supply that doesn’t vary from its target voltage when it’s under load, or powering equipment. For instance, if your phone’s power dipped significantly every time you turned the screen on, it would hamper other components’ ability to function.
Many converters, like the one that changes the voltage coming from your phone’s battery into something appropriate for its motherboard, are coupled with voltage regulator devices. Regulators can only function correctly with a range of inputs, however, so the voltage converter needs to deliver as precise of an output as possible.
Some Components Can’t Take Variation
There’s also a danger of damaging hardware by supplying it with the wrong kind of power. For instance, logic circuits like those that decode USB data or let your vehicle’s computer track performance can degrade when they encounter overly high voltages.
In some cases, these failures may be sudden and catastrophic. Other problems evolve insidiously over time. In addition to ensuring that their converters hit the right target, manufacturers must design them to output consistent power that doesn’t ripple up and down or deviate as devices age.
Are Your Voltage Converters Sufficiently Precise?
Of course, not all components demand the highest-quality power supplies, but you’re better off not taking unnecessary chances. Choosing precision-engineered voltage converters can extend your hardware’s longevity and make life far easier for end users.
