26 AUTOMATED TEST SYSTEMS www.inteprosystems.com Issue 1 2025 Power Electronics Europe www.power-mag.com entirely new system. ATE Revival ATE encompasses apparatus designed to conduct tests on a device, referred to as the device under test (DUT), equipment under test (EUT), or unit under test (UUT). Through automation, these systems efficiently execute measurements and assess test outcomes. The ATE system typically consists of hardware, software, test instruments, signal sources, and test harnesses, probes or handlers. The hardware components are typically consolidated into all-in-one test stations, which vary in size and portability from compact test stations on wheels to large stationary test towers. Each system also includes test program software, which plays a critical role in test development and the management of data collection, storage, reporting, and analysis. Engler says that these systems typically require long support paths since test requirements often extend 10-15 years. When this occurs, hardware components may fail or become obsolete. Replacing hardware components is a relatively simple process. Although ATE systems can be used for different types of tests, Engler says Intepro specializes in power electronic testing, which includes testing power converters, inverters, chargers, batteries, adapters, and other power components. Although some of the test parameters may be different, there are many commonalities in the components of such systems. Intepro’s ATE test systems feature an open architecture for hardware and software that permits complete flexibility to configure and integrate off-the-shelf instrumentation with a wide range of Intepro and customer hardware. The systems are based on universal buses (VXI, PXI, LXI, CAN, Ethernet, GPIB, and Serial) that provide choice to the customer and are not limited to one brand of equipment. Intepro offers many of the products used in test stations including AC and DC power sources, AC loads, and other standalone equipment. They offer service and repair work on all products, even on the equipment that they do not distribute. Intepro serves as a distributor for several well-known and established manufacturers. The ATE test program software is a critical component and extensive reprogramming is required when changes need to be made, often at a substantial cost. Intepro offers flexible test program software called PowerStar that streamlines and adapts to inevitable changes without extensive new programming. With more flexible software, ATE stations are ‘futureproof’ to ensure that as hardware requirements change and evolve, the test programs can adapt accordingly to ensure long-term usability. PowerStar provides hundreds of fill-inthe-blank test routines that provide a range of control, from single instrument functional control to full test procedures with easy-to-use parameter entries. Engineers can customize their programs, without having to write code or assemble graphical components. “[PowerStar] can be seamlessly integrated to operate across various hardware configurations and platforms. Even if there is already an incumbent software, our solution can be implemented and call on the other software when Outdated ATE systems, often left unused, can be refurbished or repurposed, offering a cost-effective alternative to buying new systems.
