DC-DC Converters

DC-DC converters are electronic devices used to convert DC electrical power efficiently from one voltage level to another. DC-DC converters are widely used to transform and distribute DC power in systems and instruments. DC power is usually available in the form of a system power supply or battery. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage (5V or 3.3V) which is required by the electronic component ICs, having a magnitude (and possibly polarity) that differs from Vg.


The ideal dc-dc converter exhibits 100% efficiency in practice; efficiencies of 70% to 95% are typically obtained. This is achieved using switched-mode, or chopper circuits whose elements dissipate negligible power. Pulse-width modulation (PWM) allows control and regulation of the total output voltage.


DC-DC power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives.
