What is a boost converter?
A boost converter is a step-up DC/DC converter, that is, its output DC voltage is higher than its input DC voltage. It refers to a class of switching-mode power supply (SMPS) that generally has two semiconductor switches (a diode and a transistor) and at least one energy storage element, such as an inductor. Filters made of capacitors are usually added to the output of the converter to reduce output voltage ripple.
