With the rapid development of battery technology, from consumer electronics to electric vehicles and large-scale energy storage systems, batteries have become the core energy carriers, making performance testing crucial. However, traditional battery testing methods — such as using real batteries or simple DC power supplies and electronic loads — often suffer from low efficiency, high cost, safety risks, and limited test scenarios.

Industry Background With the rapid development and widespread adoption of autonomous driving, trends such as the miniaturization, electrification, and chip-integration of LiDAR (Light Detection and Ranging) systems are gradually emerging. LiDAR is a laser-based detection and ranging system that uses a laser as the light source and employs optoelectronic detection techniques as an active remote sensing device.

EDDP refers to the total energy dissipated to produce a measurable and specific degradation indicator in the Device Under Test (DUT) during power cycling. It is an accelerated aging test method designed to evaluate the lifetime and reliability of power semiconductor modules under real operating conditions—such as frequent switching and load fluctuations.

In cutting-edge applications such as new energy, semiconductors, automotive electronics, and lasers, testing requirements are becoming increasingly complex. Traditional positive voltage power supply solutions can no longer meet the demands of chip bias testing, electrochemical deposition processes, operational amplifier power supply, and other applications requiring negative voltage and seamless positive-negative voltage switching. ITECH IT-N6300 Series triple-channel programmable DC power supply revolutionizes negative voltage power solutions with its built-in bipolar output mode. Without additional wiring, it enables efficient and stable negative voltage supply, significantly enhancing testing convenience, stability, and precision.

1. Background: International Trends in Fuel Cell Testing With the global focus on sustainable energy, fuel cell technology is being increasingly applied in transportation, stationary power systems, and portable devices. To ensure the performance and longevity of fuel cells, precise testing and diagnostic methods have become critically important. Internationally, research institutions and enterprises are dedicating resources to the development of advanced testing platforms that address various performance evaluation needs—from laboratory research to high-power application scenarios.

ITECH's popular IT-M3100 programmable DC power supply series has added a new star with the launch of a new 1000V high-voltage model. This new member not only covers power ranging from 400W to 1500W, but also is known for its compact design, 1U height and half-width rack, which is perfectly suitable for laboratory and production line system control. Not only that, the IT-M3100 series also supports synchronous control of up to 256 channels, which greatly improves the efficiency of production line testing, and is a flexible and efficient testing tool.
