Background Power management ICs (PMICs) and DC-DC converters serve as the 'energy hub' of electronic systems, responsible for power conversion, distribution, monitoring, and management. They deliver precise voltages to various loads, enable efficient charging, and enhance overall system performance.

Electrochemical Impedance Spectroscopy (EIS) is an analytical technique used to study the dynamic characteristics and interfacial phenomena of electrochemical systems by measuring their impedance response under AC excitation at different frequencies. In essence, it provides both a “fingerprint” and a “health check” for batteries.

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.

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.
