At present, the imbalance between global energy supply and demand has become increasingly pronounced, while mounting environmental protection pressures have created an urgent need to promote renewable energy generation and to strengthen power management. With the continuous expansion of renewable power generation, its impact on grid architecture, power quality, and operational stability has grown significantly.

In applications such as renewable energy, energy storage systems, electric vehicles, and consumer electronics, battery efficiency is one of the key indicators used to evaluate battery performance.

With the widespread application of power electronic devices—especially IGBT modules—in fields such as new energy and industrial drives, the requirements for performance and reliability testing have become increasingly stringent. In particular, when simulating real-world operating conditions, it is often necessary to apply a bidirectional alternating current to the IGBT module to verify its conduction, cutoff, and current-handling capabilities.

With the widespread application of semiconductor lasers in fields such as industrial processing, medical equipment, and optical fiber communications, the performance testing requirements for their core component—the fiber laser—have become increasingly demanding. Fiber lasers, known for their lightweight design, high power output, and excellent stability, offer distinct advantages over semiconductor and solid-state lasers.

In energy storage systems, the testing and validation of the battery management system (BMS) is a crucial part. To ensure that the BMS can accurately collect voltage and current information and respond correctly under various complex battery states, it becomes especially important to simulate the behavior of the cells and packs. The IT2700 Multi-channel Modular Power System, with its powerful multi-channel serial and parallel capabilities, provides an ideal solution for energy storage BMS testing.

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.
