DC DC Converters: R1D12-2412/H Application Field and Working Principle

DC-DC converters are electronic devices used to change/convert a direct current (DC) input voltage into a different direct current output voltage. They are frequently used for when the desired output voltage is lower than the input voltage, for greater current capacity, or for DC/DC conversion, such as in solar systems to convert between 12V and 24V. The R1D12-2412/H is one kind of DC-DC converter and this document outlines the application field and working principle of it.

Application Field

R1D12-2412/H is a DC-DC converter used for converting from 12V to 24V. It is typically used in applications where 12V is needed but the available power is greater than 12V. The converter can provide up to 240W of continuous power when exposed to an input voltage of 12V. It is compatible with a wide range of input voltages as it can operate efficiently between 6V and 60V with a hardwire input. The output voltage is regulated between 19V-17V. This makes it suitable for a variety of applications, such as powering LEDs, powering communications systems, etc.

Working Principle

The R1D12-2412/H DC-DC converter utilizes a synchronous buck topology with an internal high-frequency switching technology to increase efficiency and reduce input and output ripple. The converter consists of an input power stage, a control stage, and an output power stage.The input power stage contains a rectification diode, which converts the input voltage to a direct current. This direct current is then switched with the output voltage determined by the control stage. The control stage consists of a control circuit with pulse width modulation (PWM) that regulates the output voltage and current.The output power stage consists of a switching transistor that is controlled by the control circuit and an output inductor that stores energy from the input voltage. The inductor acts as a filter and creates a steady output voltage as it transfers energy to the output.In conclusion, the R1D12-2412/H DC-DC converter is an efficient and cost-effective means of converting 12V to 24V for a multitude of applications. Its internal high-frequency switching technology and synchronous buck topology ensure reliability and performance while its wide input voltage range makes it suitable for a variety of needs.
