A boost converter (or step-up converter) is a DC-DC converter that accepts an input DC voltage and produces a higher output voltage than the input.
With the ability to adjust the output voltage, it is very useful for small projects such as a solar energy charger for notebook or other devices.
In battery-powered systems often they consist of many cells arranged in series to obtain higher voltages. It is not always possible, for lack of space or for weight issues, to put so many batteries in series especially in applications where high voltage is required. The boost converters may increase the voltage and reduce accordingly the number of cells necessary for this purpose. Two typical applications in batteries that use boost converters are hybrid electric vehicles (HEV) and lighting systems.
The Toyota Prius contains a motor that uses voltages of approximately 500 V. Without a boost converter, the Prius would require 417 batteries to power its electric motor. In fact the Prius uses only batteries 168 and then elevates the battery voltage from 202 V to 500 V. The boost converters also feed on much smaller scale devices, such as portable lighting systems. A white LED typically requires 3.3V to emit light, and a boost converter can raise the voltage of a single alkaline cell 1.5 V to power the lamp. The boost converters can also produce higher voltages to operate the fluorescentia cold cathode tubes (CCFL) in devices such as back illuminators LCD and flash lamps.
