DESIGN AND CONSTRUCTION OF A DC – DC CONVERTER

Description

DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. Every electronic system is designed to operate from a supply voltage, which is usually assumed to be constant. A voltage regulator provides this constant DC output voltage and contains circuitry that continuously holds the output voltage at the design value regardless of changes in load current or input voltage, assuming that the load current and input voltage are within the specified operating range for that regulator.

In portable systems, the input voltage is often obtained from a battery. DC to DC converter type regulators receive such fixed DC voltage as input and produce the desired voltage as output which could be higher or lower than the input voltage. DC to DC converter accepts a fixed DC input voltage and produces a DC output voltage at a different level than the input.
