Case Study: OEM of DC-to-DC converters achieves 95% test-time reduction and 4× throughput increase with Keysight

Manufacturer of Automotive DC-DC Converters Slashes Test Time by 95 Percent

The OEM of DC-to-DC Converters Manufacturing Company, a leading maker of automotive DC‑to‑DC converters for EVs and HEVs, faced rapidly rising orders and a manual, one‑at‑a‑time testing process that was slow, inconsistent, and prone to data‑entry errors. They engaged Keysight to replace manual testing with a robust, automated high‑voltage test solution using Keysight instruments including the B2985A electrometer/high‑resistance meter, N8900 autoranging DC power supply, 34980A multifunction switch/measure unit, and N3300 Series DC electronic loads.

Keysight delivered an automated test system that simulated vehicle batteries, enabled simultaneous multi‑output measurements, automated data logging, and improved safety for high‑voltage work. The Keysight solution cut total test time by 95%, increased throughput 4×, provided insulation‑resistance resolution down to 0.01 fA and up to 1000 Vdc testing, and standardized test procedures across sites—significantly improving test accuracy, efficiency, and product quality.
