DC DC Converters

RV-3.315S/R8 Application Field and Working Principle

DC–DC converters are power converters, designed to efficiently step up or step down a voltage without altering the frequency. These DC–DC converters are used in a wide range of applications, from consumer electronics to aerospace systems. As such, they have different applications and operate on different principles, depending on the technology used. In this article, we will look at the RV-3.315S/R8 DC–DC converter and explore its application field and working principle.The RV-3.315S/R8 is a high-efficiency DC–DC converter, designed to convert +12V DC input voltage to a +3.3V DC output voltage. It is a top-level isolated module, providing an isolated galvanic insulation of 2500V, which ensures that the input and output are electrically isolated and remain safe from transients and other external noise. The module is fitted with 90-264V AC input voltage and integrated over-current, over-voltage, and short-circuit protections. This module can be used for low signal level power applications, such as micro-controllers, PC motherboards, RAMs, or programmable logic controllers (PLCs). Other areas where this converter could be successfully used include data acquisition systems, automated test equipment, remote telemetry equipment, or wherever mains-level power supplies are needed. Additionally, the RV-3.315S/R8 is designed for use in industrial and commercial environments, due to its wide temperature range, low EMI levels, and high efficiency. In terms of its working principle, the RV-3.315S/R8 DC–DC converter operates by utilizing two power conversion stages – one is AC to DC ( ACDC) conversion, involving a transformer and the other is DC to DC ( DCDC) conversion, involving one or more active switching elements such as a transistor or a diode. In the ACDC stage, the AC input is rectified and fed through a transformer. This increases or decreases the voltage, depending on the turns ratio of the transformer. The stepped-up or stepped down AC voltage from the transformer is then rectified and filtered to obtain a DC voltage. In the DCDC stage, the output from the ACDC stage is used as an input to one or more switching elements which convert the DC voltage to a higher or lower voltage. This is done by switching the DC input voltage very rapidly, making it appear as a high frequency square wave voltage. This is then filtered to obtain the desired DC output voltage. The RV-3.315S/R8 DC–DC converter is capable of providing an output current of up to 3.2A and offers programmable output voltage settings through onboard jumpers. The converter has an efficiency of up to 98%, and is capable of working over the temperature range of -40 to +85°C, with an output power rating of 10.5W. Overall, the RV-3.315S/R8 DC–DC converter is an ideal solution for a variety of applications requiring a high level of galvanic isolation, efficiency, and low EMI. It is designed for use in industrial and commercial environments, and offers wide temperature range, programmable outputs, and high power ratings. In terms of its working principle, the converter uses two power conversion stages – AC to DC and DC to DC – to convert the input power to the desired output level.
