How To Choose Load Regulation for Power Supplies

September 3, 2017

The most important thing that a power supply does is to maintain a constant voltage output or a constant current output. This is true whether the power supply is built into a product and provides fixed output voltages, such as a desktop computer power supply, or a power supply that is on the test bench or is part of an automated test system that must provide variable outputs. We call this ability to maintain a constant output voltage or current regulation.

Sorensen SG Series Ensures Reliable Testing for Auto Parts

August 28, 2017

One of the big challenges when designing and manufacturing auto parts is ensuring that they operate reliably in very hot environments, such as Dubai, where the high temperature can easily reach 40˚C. Of course, they must also operate reliably in very cold environments, such as Siberia, where the thermometer can drop to -40˚C or below. You certainly don't want parts to fail when you're zipping down the road at 200 km/hr. because they can't take the heat (or the cold).

RS Series High-Voltage Option Eases PV Inverter Testing

July 14, 2017

As the number of photovoltaic power-generation systems continue to increase, the requirements for photovoltaic inverters are evolving as well. Conventional electrical characteristics such as over-voltage, over-frequency, anti- islanding intended to verify the inverter’s ability to tolerate power grid fluctuation are changing to meet varying requirements of the modern grid. In addition, the introduction of new requirements for low voltage ride through, high voltage crossing, and reactive power injection mean the inverter must be able to provide appropriate compensation when these grid conditions occur.

How To Use an Adjustable Power Supply with Tracking Outputs

May 15, 2017

Many op-amp circuits used in analog applications, such as signal conditioning for high bit count analog-to-digital converters require the use of both positive and negative power supply voltages, as shown in Figure 1. Supplying both positive and negative voltages allows input signals and output signals to swing both positive and negative. You could power these circuits with an adjustable power supply with two outputs and adjust them separately—one to the positive rail voltage, say +12 VDC or +15 VDC and the other to a similar negative voltage.

How To Calculate Voltage Drop to Prevent System Problems

January 20, 2017

One of the problems we frequently encounter in the field is that power supply users fail to take into account the voltage drop in the wires connecting a power supply to a device under test (DUT) or other electronic system. When a load draws a high current, the voltage drop across the power leads could be high enough to cause a device under test to fail or cause a system to malfunction.

Generate Fast Transient Tests with an Electronic Load

July 23, 2016

To ensure that automotive electronics can withstand the voltage transients induced on the power bus, companies use expensive arbitrary waveform generation and coupling networks during the design phase. For production test, however, a simpler and less expensive means for simulating bus voltage variations and transients is required. For many transient tests, all you need is a switching power supply and an electronic load.

External Capacitor Prevents Problems with High Ripple Current Loads

January 18, 2016

In many applications, a DC power supply has to drive a load with a large ripple component. Examples of this type of load are DC-AC inverters, DC-DC converters, and DC motor loads. Linear supplies can normally handle this kind of load easily, but when you use a switching power supply, such as the Sorensen SG Series or Sorensen ASD Series, to drive this type of load, you may encounter some unexpected (and undesirable) problems.

Transient response is important when loads change rapidly

September 8, 2015

Transient response is a measure of how well a DC supply, such as the Sorensen SG Series, copes with changes in current demand or how well the supply follows load impedance changes. This is an important specification in many applications, such as mobile phone testing and testing automotive relays and fuses. A good understanding of this power supply characteristic will help you choose the right supply for your test application.

Remote sensing compensates for power lead loss

June 26, 2015

When a load draws a high current, the voltage drop across the power leads could be high enough to cause a device under test (DUT) to fail or cause a system to malfunction. The solution to this problem is to use remote sensing. By adding a second set of wires—the sense wires—you can ensure that the proper voltage level is at the DUT or system's power terminals.

Tips to improve DC supply slew rate

March 18, 2015

The slew rate of a DC power supply is the rate at which the output voltage and output current changes. This characteristic is important in many applications, especially automatic test applications, as the faster a supply reaches a programmed voltage or current, the faster a test will run.

Are linear supplies or switching supplies the best choice for your test system?

March 13, 2015

The first choice you must make when purchasing a DC power supply for a test system is whether to 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 levels (typically less then 500 Watts). Most linear DC power supplies are benchtop supplies.

Choose the right equipment for automated EV testing

March 11, 2015

Testing the electric motors and the electronic control modules found in today's electric vehicles (EVs) and hybrid electric vehicles (HEVs) is in many ways more challenging than testing internal combustion engines and their control modules. For one thing, HEV electric motors spin faster than internal combustion engines. They also must change speed more rapidly than internal combustion engines, and because some are designed to also generate energy, the test system must also measure the electrical output as well as the mechanical output of the motor.
