DC-DC converters are electrical systems that convert power from one direct current (DC) electrical voltage level to another. They are often used to produce a regulated output voltage from a higher or lower input voltage. The RTS-1224/H-R is a high-reliability, wide-input-range DC-DC converter designed for a range of aerospace and military applications, including vehicle-mounted systems. This article will discuss the applications of the RTS-1224/H-R and the working and design principles that make it an effective DC-DC converter.

Applications

The RTS-1224/H-R is a high-power DC-DC converter capable of delivering up to 24 VDC from a wide input range of 8 to 36 VDC. It can also operate from a single 3S lithium-ion battery, making it an ideal solution for applications that require a reliable source of regulated power. Its rugged construction makes it suitable for vehicle-driven applications, such as on-board equipment, computers, and communication systems. The RTS-1224/H-R is particularly suitable for military and aerospace applications due to its robustness and reliability.

Design and Working Principles

The RTS-1224/H-R has two major components. The first is a switched-mode power supply (SMPS) consisting of an inductor, an active switch, and a diode. The second is the linear regulator, which introduces a resistive element across the output of the SMPS to ensure that the output voltage remains steady and constant. These two components work together to provide a regulated 24 VDC output from an 8-36 VDC input.

The SMPS component of the RTS-1224/H-R uses the “flyback converter” topology. This involves a single active switch that is turned on and off by a control circuit. The inductor stores energy during the “on” phase, and the diode allows the stored energy to be released during the “off” phase. This conversion process is repeated continuously to convert the input voltage to the desired output voltage.

The linear regulator is essentially a feedback-controlled voltage divider. It uses a voltage reference and a feedback resistor divider network to create a stable regulated output. The feedback network is carefully designed to maintain a regulated output voltage in the presence of varying input voltages. It also provides a mechanism for current limiting, over-voltage protection, and short-circuit protection.

Conclusion

The RTS-1224/H-R is an efficient and reliable DC-DC converter suitable for a range of aerospace, military, and vehicle-mounted applications. It uses the flyback converter topology in combination with a linear regulator to deliver a regulated output voltage from a wide range of input voltages. Its robust construction and reliable performance make it a trusted choice for powering a variety of systems in extreme environments.
