DC DC Converters - TMR 9-1222

DC DC converters, in general, utilize a direct current (DC) source supplied to an inductor, transformer, or capacitor to boost (step up) or buck (step down) a voltage for various applications. The TMR 9-1222 is the latest state-of-the-art DC DC converter designed by TT electronics for use in a variety of high power applications. This document will detail the converter\'s various application fields and working principles.

Application Fields

The TMR 9-1222 is designed for a variety of high power applications, including defense and aerospace, alternative energy, telecommunications, heavy industry, and transportation. The converter is specifically designed for deployment in military and aerospace applications where shock and vibration protection are important, or where high power density and efficiency are required. The TMR 9-1222 has the capability to withstand wide input voltage ranges from 18 to 760 volts AC, and is capable of switching frequencies of up to 50 kHz, allowing for more efficient conversion and improved thermal performance. The converter is also certified to meet the MIL-STD-704A, MIL-STD-810E, and DO-160F military standards, making it suitable for deployment in even the toughest and most demanding conditions.

Working Principle

The TMR 9-1222 DC DC converter is designed around the buck switch-mode topology. This topology works by controlling a switching device to switch on and off a current path between an input voltage source and an inductor. The switching action of the device creates a pulsed current signal, which is then transferred to the output of the converter. The current is then rectified, converted, and regulated by a pair of integrated feedback loops. The first feedback loop senses the output voltage of the converter and adjusts the duty cycle of the current to maintain the desired voltage level. The second feedback loop monitors the input voltage of the converter and adjusts the duty cycle accordingly to maintain the output voltage. The TMR 9-1222\'s buck topology allows the converter to efficiently regulate and convert voltages from a wide input voltage range while maintaining high efficiency, improving the converter\'s overall performance.

Conclusion

The TMR 9-1222 is a state-of-the-art DC DC converter designed for deployment in a variety of high power applications. The converter is designed around the buck switch mode topology, which allows the converter to efficiently regulate and convert voltages from a wide input voltage range while maintaining high efficiency. The TMR 9-1222 is also certified to meet industry leading military standards, making it suitable for use in even the toughest and most demanding conditions.
