High-performance devices need a stable and well-regulated power supply voltage. However, if your device needs a voltage different from what it obtains from a power source, a DC/DC converter is the best choice. It helps you optimize energy efficiency in battery-powered, portable devices that need to conserve power. DC-DC power converters also keep the output voltage stable, although input voltage has variations. But, which DC-DC power conversion device is the right choice for your application?
DC/DC converters- Available in different categories
Boost/step-up converters
Boost power converters are intended to step up the input voltage to a higher level. They are useful, especially when you need to increase the voltage to meet the load requirements. But, it is sometimes essential to determine the weak power supply.
You may use the converter for your battery-powered device where the battery voltage is lower than the required amount.
In a boost converter, energy remains stored in an inductor with the switch being closed. It is then released through the diode after opening the switch. So, it results in an increase in voltage.
Buck/step-down converters
Buck power converters are highly popular DC-to-DC conversion devices, which have step-down functionality. They are efficient at lowering high-input DC voltage to reduce the output voltage. Thus, if the voltage in the power source is higher, you need this DC-DC converter.
Buck converters are often used in automated equipment for voltage adjustments and meet various components’ needs. For instance, you run a system on a 24-voltage power supply, but it needs a buck converter to operate a 12V sensor.
Efficiency is the biggest advantage of using the buck power converter. The best quality power conversion device generates minimal heat and reduces the cost of operational power supply. Thus, it ensures a longer lifespan of the connected gadgets and the converter. Like the boost converter, the buck converter has a switch that remains closed to store energy in an inductor. The amount of the transferred energy is determined by controlling the switch.
Buck-boost power converters
If you want a versatile solution, buck-boost power converters are the right choice. These converters come with combined functionalities of boost and buck converters. They will decrease or increase the input voltage based on your device’s needs. They are used in modern systems with variations in input voltage.
Innovatively designed power converters retain a consistent output voltage even though input conditions vary significantly. They first step down the voltage and then step it up with a special mechanism. The properly controlled switch timing helps with precise output voltage adjustment.
Uses of DC-DC converters
The most common applications of buck converters are
- Small motors in a large device
- LED lighting system
On the contrary, boost converters are used for
- Communication devices
- Remote sensors
Buck-boost converters also have several applications
- Portable gadgets
- Automotive electronics
- Systems with different power sources
So, identify your needs before investing in power converters. Make sure your power conversion device complies well with safety regulations and industry standards. These aspects are highly important for operational integrity. Moreover, you must not overlook the physical space where the converter needs to be installed. For some applications, you need a compact power converter to facilitate seamless integration.
