DC-DC Converters are used across many industries, from communications to transportation, and are considered essential technology these days due to the ease with which they can convert energy from one DC source to another. The TON 15-4813 is a DC-DC converter designed to convert 6-48 VDC to a sine wave output of 13.8 VDC @ 3.5 A with a nominal ripple of 200 mV peak peak. It offers adjustable set points of 0-24 VDC for minimum voltage, maximum voltage, and constant current.

The TON 15-4813 is designed using a high frequency, switch mode topology in order to efficiently convert the available energy to a sine wave output while avoiding significant losses. This is done by using a series of high-speed switching transistors and accompanying control circuitry to convert the input voltage into a square wave. This square wave is then converted to the sine wave by a pair of filters called an LC filter. The output of the sine wave is then fed into a rectifier, regulating the DC output to the desired set point.

The TON 15-4813 is designed to be very efficient, dissipating only 4 watts despite converting higher input voltages into 13.8 VDC. This efficiency is also made possible due to its switching design, operating primarily in the "on" and "off" state. When the output current increases, the control circuitry reduces the switching frequency in order to reduce the majority of the current ripple. This allows the power transistor switching losses to be minimized.

In order to ensure the TON 15-4813 operates as reliably and efficiently as possible, the unit is designed with an overleak protection circuit, which prevents the output current from exceeding the set point by more than 25%. An undervoltage lock out circuit is included that will shut down the converter if the input voltage drops below a minimum level, also preventing any damage to connected equipment. Finally, an overtemperature shutdown is included that will reduce the output current and voltage in order to protect the converter from thermal damage.

The TON 15-4813 operates with any source of 6-48 VDC and is widely used where direct conversion from one DC source to another is required. It is one of the most efficient and reliable converters on the market and is well suited for applications requiring the conversion of 6-48 VDC to 13.8 VDC.
