Does Your Railway Application Possess the Right DC DC Converter?

Today I am going to discuss about the DC DC converters (which is also known as linear converter or switching regulator). Learn about its design, benefits, and features.


• Design of the converter:


There are a number of designs that the engineers have planned. When you select the appropriate low power linear converter for application, find the right design that is suitable for your application. The engineers understand the level of isolation that is required in the converter. When the engineer's manufacture railway DC DC converters, they know how much the converter can tolerate voltage fluctuations. Addition to this, they also know the different types of protections that must present in the converter. These designs combine with different packaging types. The different designs create a broad number switching regulator.


• The requirement of input voltage:


The input of a linear converter is tied to the output supply in the power system. The engineer has to know the required input voltage that is necessary for the converter. There are a number of different input options and which options should be chosen depends on the stability of the voltage. The fixed input voltage can be used when the voltage to the input is very stable. If, on the other hand, the converter is connected to the fluctuating supply of current, like in a battery. A much wider input range is required for the changing input voltage conditions.


• Fixed output feature:


An engineer must take the required output voltage and it is the easier decisions they can take. The decision on the output voltage is decided by the load requirements of the application. In such a case, to manufacture high quality industrial DC DC converter, engineers need to determine whether the application needs a single load or two loads.


• The function of the power converter:


The switching regulator can be used to step up a voltage, step down a voltage, or even invert a voltage from positive to negative. These are selected and dependent on the type of power converter’s design. The most common function is to step down the DC voltage from a higher voltage to a lower voltage.


• Isolation feature:


The linear converter is designed to provide isolation in a system. This creates a barrier which can be used for noise isolation and safety protection. This feature of railway DC DC converters has a resistance function. The isolation voltage is defined as the maximum voltage that a device can withstand for a fixed time period. The required isolation voltage will depend on the device. The higher isolation is required in medical applications.


• Regulated and non-regulated feature:


Another feature of the converter is the regulated and non-regulated converter. These are the two primary categories switching regulator. The regulated converter can maintain the output voltage within a specified range when the input changes. Regulated converters are used in applications where the input voltage range is not well regulated. Non-regulated devices are used when the voltage is well regulated and voltage changes are minimal. The non-regulated devices are generally smaller and these are less expensive than regulated linear converters. The regulated converter has a wide input range. And, the non-regulated converter has a narrow input range.



Bottom Line:


When selecting a switching regulator, there are a number of criteria. These criteria include the required protections, regulation, isolation, the function of power conversion, outputs, inputs and, packaging. This converter has a wide variety of options and the engineers should meet most customer needs. This power supply provides an engineer with multiple options. The converters are available in a range of single and dual output voltage configurations.
