Test automation implementation in power supply development and verification

Today, new product launch cycles are getting shorter and shorter, and product quality and consumer reputation are becoming more and more important! Engineers engaged in product R&D, design and testing must also actively respond. While improving product testing, they should compress testing time to gain a head start in the competition. As we all know, test automation can greatly improve efficiency, but in research and development, many hardware engineers are often overwhelmed when faced with complex instrument connection control and programming, and still use manual panel operations to complete tedious tests, so overtime is almost every day. Standard for an engineer.

Standard for an engineer.

Many engineers in the power supply industry, especially power supply hardware R&D engineers, still operate the instrument panel manually, record the measurement data with paper and pen, and then enter it into the computer for data analysis.

Test automation implementation in power supply development and verification

It’s time to change this inefficient testing approach.

Keysight’s BenchVue / Test Flow software platform supports various types of measuring instruments, enables remote virtual instrument setting and reading, and can quickly and flexibly drag and drop your own steps without any coding experience. Automated testing to obtain massive test data and data analysis or export.

Into BenchVue&Test Flow

1. Virtual instruments and multiple instruments are controlled on the same screen!

2. What you see is what you get, the setting or measurement of the instrument can be directly dragged to any position in the sequence to create a test flow.

3. Modify the name or logo, process numerical operations, automatically export files, etc.

4. Run the sequence, draw XY curves, such as efficiency Eff vs. output power curve, output voltage Vout vs. output power curve, etc…

Combination scheme of several different types of power test

1. The N6700 modular system-ready power supply enables automated testing of multi-channel DC-DC.

The N6700 adopts a modular design, which separates the power module and the host. While greatly improving the power density, it can be arbitrarily assembled with modules of different voltages, power, functions and performance, with excellent flexibility and expansibility; at the same time, the modular design It also greatly improves the reliability of the system, and users can replace modules by themselves, simplifying and reducing the difficulty and cost of daily maintenance.

In the figure, the N6700 single machine is equipped with one DC power module and three load modules, which are used to test the three output DC-DC modules, and cooperate with Test Flow to realize the efficiency curve scanning of small steps, the cross adjustment rate under various load combinations, etc. A quick measure of performance.

2. The RP7900 APS advanced power supply system realizes automatic testing of bidirectional DC-DC.

RP7900 APS regenerative advanced power supply system, maximum voltage 2000V, positive and negative bidirectional seamless current (source and load integrated), maximum current ±800A, 0.04% measurement accuracy (power analyzer level), single power 30KW, parallel to 600KW. It can meet the precise power supply and measurement of various medium and high power systems such as battery packs, PCS, photovoltaics, energy storage, and fuel cells of new energy vehicles.

3. AC6900 high-performance three-phase AC power supply and RP7900 realize OBC and high-power AC-DC automatic testing.
