High Ripple Current Loads 13 Article: Advanced Electronic Power Simulation 14 Article: How to select an AC power source Technical Note: Amrel Systems PD20-2DA supplies provide power to the device under test as well as test stimulus. In some cases, the supply used to provide power to the DUT also provides a test stimulus by simulating the operating environment.

Amrel Systems PD20-2DA For example, while most automotive electronics run at a nominal 12 VDC, the maximum input voltage may be as high as 27 VDC. Necessities such as these determine power supply requirements.
Power Supply Calibration
Let s take a look at other common power supply specifications that you need to consider when selecting a power supply for an automated test system. Linear or Switching Supply?
The first choice you must make when purchasing a DC power supply is whether Amrel Systems PD20-2DA select a linear supply or switching supply. Linear power supplies offer low ripple and noise specifications and have fast transient behavior. They are, however, inefficient and generate a lot of heat. They are also quite heavy.
As a result, most engineers find them desirable only at lower output power Amrel Systems PD20-2DA typically less than watts. Most linear DC power supplies are benchtop supplies. If your system requires more output channels, or higher output power, then using switching supplies is a better option.
They provide higher power density than linear supplies. By using switching supplies, you can have 12 DC outputs, providing up to 4, W of power in the same rack Amrel Systems PD20-2DA.

Switching supplies are easier to control than linear supplies and cost about the same per channel. The water-cooled packaging allows it to be used in environments that normally Amrel Systems PD20-2DA air-cooled power supplies. Even in applications where low ripple and noise output are required, switching supplies are often more than sufficient.
Recent developments in power electronics, such as zeroswitching, have dramatically improved the ripple and noise specifications of switching power supplies.
When you also consider that switching power supplies are more flexible than linear supplies and provide higher power density, it becomes apparent they are the favored choice Amrel Systems PD20-2DA all but a handful of applications. One application for which a linear benchtop supply may be the best choice is when testing communication devices such as a radio or mobile phone or the demodulator module of a radar system. These devices have very sensitive discriminator or demodulator circuitry that work best with a low noise figure.

To test the true performance of these units, we need to ensure that the DC power supply does not add any parasitic noise to the test setup, and because linear supplies have lower output ripple and Amrel Systems PD20-2DA than switching supplies, they are a better choice for this application. Linear supplies are also a good choice when power requirements are low. The main benefits of a switching supply are only relevant Amrel Systems PD20-2DA higher output power levels.
It is, therefore, less expensive to use linear DC Amrel Systems PD20-2DA supplies in applications that do not require more than W to W per DC output channel. At this point, it is also important to consider the total power output of all the DC channels in your system.
