DC-DC converters are electronic devices which convert one form of electrical energy into another form of electrical energy. They are widely used in in various applications such as automotive, computing, telecom, and aerospace fields. VRAH-01H1A00 is a DC-DC converter module designed specifically for high-reliability applications. This article aims to discuss the application field and working principle of VRAH-01H1A00.

Application Field

VRAH-01H1A00 is a wide-input voltage range DC-DC converter module with high power efficiency, offering an optimal solution for avionics. It is designed to provide always-on power to mission-critical equipment on aircraft, including highly sensitive avionics systems, as well as other power-sensitive applications. It can be used in a variety of applications with input voltages ranging from 18VDC to 250 VDC and an output power of up to 300W. Furthermore, with its wide temperature range and excellent thermal performance, the VRAH-01H1A00 DC-DC converter module can meet the most stringent requirements of various aerospace application environments.

Working Principle

The VRAH-01H1A00 DC-DC converter module uses a synchronous rectification technology to increase the conversion efficiency and reduce the power consumption and component count of the power system. It supports a maximum input voltage of 24 V, a maximum output voltage of 30 V and a maximum current load of 10 A. It also comes with an integrated protection feature that prevents overload and over-temperature conditions.

The DC-DC converter module contains an internal controller which converts the input voltage into a regulated output voltage. The controller regulates the output voltage by varying the duty cycle of a switching transistor connected between the input and output connections. Because the transistor switches in short pulses, the input voltage is converted into an output voltage with greatly reduced ripple. The modulated switching frequency of the transistor determines the maximum rate of current flow. This switching frequency can be adjusted according to the desired output current.

The VRAH-01H1A00 DC-DC converter module is designed to provide efficient, reliable, and cost-effective power solutions for aerospace applications. It is built with a wide temperature range and high efficiency, making it ideal for use in harsh environments such as aircraft and spacecraft. Additionally, its integrated protection features ensure system safety and reliability.
