Boost converters or step-up converters are types of switch mode DC-DC converters designed to boost or step up the input voltage from the supplied output voltage. They provide a higher output voltage than the source power supply. Like a buck converter, a boost converter also features two semiconductors, a capacitor, and an inductor for energy storage.
Input Sources for Boost Converters:
The input direct current source to the boost-converters comes from many sources, such as:
- Batteries
- Rectifiers (AC from mains supply)
- Fuel cells
- Generators (Electric or DC)
- Solar Panels.
What are the benefits of boost converters?
They offer various advantages, such as:
- They provide high output voltage with low distortion and low operating duty cycles.
- Reduce cost and offer to enhance the functionality of the device to be used.
- They are also a source of good quality waveforms even in the presence of the line frequency.
Difference Between a Buck and a Boost Converter:
The boost converter differs from buck converters in that the output voltage of the boost converter is greater than or equal to its input voltage.
Where are booster converters used?
They are widely suited for a wide range of applications and devices, such as:
- Power amplifier applications
- Batteries
- Consumer Electronics
- LCD, OLED displays
- Hybrid vehicles
- DC motor drives
- Haptic displays
- Mobile phones
- Tablets
- MP3 players
- Adaptive control applications
- Bar-code scanners
- Heaters
- Power factor correction circuits.
