As the name implies, voltage converters are DC-DC converters, typically electronic circuits or electromechanical devices, that transform a direct current (DC) input voltage to a different DC output voltage. They are used where the operating voltage for some electronic devices vary, making it necessary to provide a separate voltage for each device.
AC power allows the variation of voltage levels via a transformer. Unfortunately, this doesn't work with DC power. However, many electronic devices operate at different DC voltage levels. Hence, sometimes it is necessary to convert the power, for example, from a 24V truck battery to 12V in order to power a car radio.
Similarly, modern portable electronics, such as smartphones, laptops, and cameras, often require various voltages for different components within the same device, making DC-to-DC conversion essential for efficient operation. So, it's necessary to use a voltage converter to step up or down the power, ensuring it's safe and suitable for the specific device or application.
A wide variety of types are available to suit different needs. Some DC-DC converters will step up the power, others will step down, and some can do either. It's important to know the specifications of the converters being used to avoid damaging equipment. Types of DC-DC converters include:
This power voltage converter isolates the output from the input with internal transformers to convert the input to a different output voltage. They have higher isolation voltage properties and, unlike the non-isolated versions, have the ability to block noise and interference.
These devices do not have any isolation between the input and output and are typically used for smaller voltages. One disadvantage of using this type of power voltage converter is that they do not offer much protection against high electrical voltages.
This type of power voltage converter takes the DC power that comes in from the vehicle's battery and steps it down to make it usable with personal devices such as DVD players, phone connectors, CD players and more.
Named because it 'bucks' against the input voltage, this power voltage converter produces an output that is less than its input.
A boost DC-DC converter does the opposite of a buck DC-DC converter and steps up the voltage output.
This type of converter is similar to buck-boost converters. The biggest difference is really the name. The Cuk was named after Slobodan Cuk, the man who created it.
This type of power voltage converter is used to step the voltage up or down in applications that have low power.
DC-DC power voltage converters offer numerous benefits, such as:
Power voltage converters are vital components across a spectrum of industries, ensuring efficient power management and compatibility between diverse electrical systems.
When employing power voltage converters, safety is paramount. Therefore, you should always ensure proper handling and installation according to manufacturer guidelines, including adequate ventilation and protection from moisture.
In high-risk environments or when working with high voltages, it is crucial to prioritise workplace safety by using isolated DC-DC converters to prevent electric shock and potential equipment damage. This includes adhering to electrical safety regulations, using appropriate protective gear, and ensuring proper grounding and insulation of all electrical components.
