Battery Emulation Testing for Repeatable and Efficient Results Wednesday, April 24, 2024 von: Craig Frahm

How can we test battery-powered electronics? If we test with a battery or a battery pack, we are working with a voltage source that does not have a constant output. The battery output is not repeatable and must be disposed of if it is a primary battery or re-charged if it is a secondary battery. We could use a conventional power supply, but we cannot ensure that the electronics perform correctly …

Safeguarding DC Programmable Power Supplies: Protecting Against Inductive, Capacitive and Oscillatory Loads Friday, August 25, 2023 von: Craig Frahm

Connecting a DC power supply to a load may seem clear-cut, but it can become challenging in certain situations. While power supply manufacturers design their products to be stable when powering various loads, certain load characteristics can pose risks and even damage the power supply’s output stage. Inductive and capacitive loads and loads with rapid changes in load current can create conditions …

The Benefits of Autoranging vs Conventional DC Power Supplies Monday, May 1, 2023 von: Craig Frahm

How Autoranging Saves Capital Costs and Rack Space (and How True Autoranging Saves Even More!) You need a high-capacity power supply. Should it be a conventional power supply with a rectangular output characteristic or a power supply with an autoranging, constant power output characteristic? That depends on the load the power supply must support. If the load is a constant power output device such …

Solutions to the Challenges of High Power ATE System Design Tuesday, March 7, 2023 von: Craig Frahm

So, your assignment is to design a new high-power automated test equipment (ATE) system for a new product. Your challenge is to design a test system with maximum test performance to fully test the product within a pre-defined budget. Oh yes, the system must be reliable to avoid lost production time. The system must be online at all times except for maintenance shutdowns. Also, both the capital and …

Repurposing and Recycling EV Batteries Tuesday, July 6, 2021 von: Craig Frahm

It’s no secret that there are more electric vehicles (EVs) on the road today than ever. Since 2015, the number of electric vehicles worldwide has grown from 1.4 million to more than 8 million today. Because EVs emit far fewer hydrocarbons than vehicles powered by internal combustion engines, they are an important part of the plan to combat climate change. EVs do, however, present other challenges …

What Power Supply Trends Exist in the Semiconductor Market? Wednesday, April 14, 2021 von: Craig Frahm

As the semiconductor industry begins to heat up in 2021, at least according to Semiconductor Industry Association’s optimistic forecasts device demand, test engineers are going to need to find new ways to cool down their power supplies. While in the past water-cooled power supplies were only available as part of a custom-designed solution, now companies are offering advanced water-cooled power …
