A DC to DC converter is a device used in electrical engineering to alter the voltage of one DC device to that of another. In the past, these devices were often large and bulky, with questionable efficiency. However, recent developments in these converters has provided a wide array of compact and convenient products to the consumer. These developments have primarily been enabled by hybrid circuits, which make it possible for consumers to install small converters that still maintain an efficiency rate of 85 percent of higher.

A DC to DC converter is often found in any small electrical device, especially portable electronics. This can include cell phones, PDAs, laptop computers, and MP3 players. DC is advantageous in these devices because, due to space limitations, it is often difficult to install several batteries to power different aspects of the devices. The DC converter regulates the power supplied by the product's batteries, and disperses it throughout the device.

DC to DC Converter Methods of Transformation

There are several methods that a DC to DC converter might use to transform the flow of voltage. On of the most common involves the use of a voltage divider. A voltage dividers installs a series of registers, in conjunction with the voltage. As the electricity flows through the divider, it is incrementally reduced, lowering the voltage to the desired amount. While voltage dividers are in wide use, there are some drawbacks when it comes to a few specific situations. These drawbacks include the generation of excessive heat, the inability to convert from a low voltage to a high voltage, and the inability to generate negative voltages.

Devices that may be underserved by the voltage divider method of a DC to DC converter, may be powered by an alternate means of conversion. A more recent, and popular means of DC to DC conversion involves the additional use of AC current. In this situation, the DC current is first converted to AC. At this point, the voltage is altered, either up or down, while the current is in the more easily manipulated AC state. Once the desired voltage is attained, the current is changed back to DC.
