The Advanced Guide to DC DC Converter for Industry Use

by Isabel Blamey Professional writer

This article is the guide to many Australian instruments manufacturer and buyers who discuss the low power DC DC converters for specific applications and designs. When you are specifying a DC DC converter (which is also called a linear converter or switching regulator) for your industry, you can choose the converter which has an easy task or a complex task. Obviously, you need to select one with the right output voltage, as well as input voltage range. It is actually the easier part.

But there are two other issues you need to consider: what is the power distribution efficiency you will be using through railway DC DC converters? What is the supply path? I'm not talking about the internal components of the linear converters. There are some commonly used design ideas. But to the user, the supply is dependent on the input, output, and the performance of the converters.

• How the converters distribute the power?

If you need to supply single DC power from a single circuit to the application, you have to depend on the power converter. Consider yourself lucky. Many applications need that single voltage or need different voltages. Right here, you have the choice of the larger supply or multiple supplies of the currents.

The DC line can feed a single larger DC DC converter or several smaller ones even with the same output voltage. Many applications use power distribution, where the DC DC supply has one or more converters which in turn transform the DC voltage from the DC DC supply into lower-voltage DC rails.

Many installations use a single industrial DC DC converter to supply a one DC voltage which turn provides the final DC rail voltages. Which kind of DC DC converter is needed, you should simplify this. In most designs, there is only a single voltage, such as 48V DC or 12 V DC or some more complex systems. Therefore, you can focus on finding a DC DC supply which provides the desired voltage as sufficient current.

• How to reduce output noise using the non-isolated linear converter?

A system requires multiple voltages. The linear converters are often used with single output power supply, rather than using a multiple output DC DC supply. This can reduce wiring complexity and save cost if not all the voltages are needed for every system configuration.

The system circuit can be noise sensitive, particularly in high-resolution microscopes and medical equipment. Multiple DC DC converters operate at different switching frequencies, particularly if the frequencies vary with input voltage or output load. The fixed frequency converters on individual switching circuits can lead to sub-frequencies.

Significant filtering on the inputs and outputs of the converters can be complex and very time-consuming. Use a fixed switching frequency switching regulator. It is made simpler and easier. There are some linear converters that have a synchronization capability. The new series of non-isolated railway DC DC converters have this option and multiple units. It can be configured to the operating frequencies. In addition to output noise reduction; the new series offers a function, which reduces the input current and noise.

• What will you get by powering drives with linear converters?

The linear converter is an ideal combination of the voltage of a transistor and the drive. The applications at high power using this device with effective capacitances, although the capacitances need to be charged to turn the converter on and off. The current do so cause the significant power in voltage drops in the circuit are paralleled. At high power, converters typically use configurations to generate DC to transform other loads. The circuits at high voltage and high frequency are associated with the power rails.

Bottom Line:

Switching regulators are providing drive power for specific performance applications. It provides significant advantages over alternative techniques with security and efficiency under continuous operating conditions. The demand for this converter has due to the need for standardized switching power supplies. In addition, input and output ports require isolation to increase safety – this is another requirement that this converter can fulfill.
