After touring the SNEC 2026 exhibition, one distinct impression is that the topics commanding attention in the inverter industry are shifting. This is a key question that CHIPSENSE focuses on deeply.In previous years, the discussion centered largely on metrics such as conversion efficiency, power de...... READ MORE

AbstractSNEC 2026 Shanghai PV Exhibition sends a clear signal: optical-storage integration is changing from an optional configuration to a standard feature. This article provides an in-depth analysis of the two core thresholds of grid-forming technology for current detection, the measurement challen...... READ MORE

The massive, multi-hundred-billion-parameter AI models that have taken the internet by storm appear, on the surface, to be a contest of algorithms and computing power; however, within the realm of "three electrics"—electrical energy, electronics, and power systems—a clear consensus has emerged: the......

AbstractChina has over 12 million EV chargers in operation, with highly inconsistent leakage protection configurations. A large number of in-service chargers still use Type AC/A residual current devices (RCDs), which offer almost no detection capability for smooth DC leakage current. The GB 44263-20...... READ MORE

Have you ever stopped to consider this scenario?Imagine an AI accelerator card—worth hundreds of thousands—running at full power to train a massive model with hundreds of billions of parameters. Suddenly, the power grid experiences a flicker—a disturbance lasting less than 50 milliseconds. What is t...... READ MORE

Have you noticed an incident in the energy storage industry last year?A grid-connected acceptance inspection of an energy storage station was successfully completed for all equipment, but got stuck on one single point: the data from the DC-side fault recording could not match the on-site measured va......

In 2026, domestic air conditioner production in China exceeded 210 million units, with inverter models accounting for more than 70%. However, it is an open secret in the industry that the actual energy efficiency of many inverter air conditioners differs significantly from the labeled APF values. Ac...... READ MORE

When I first started developing inverters, my understanding of current detection was relatively simple. I only focused on indicators such as accuracy and bandwidth, and I could basically determine the solution by checking parameters during model selection.However, as the project power gradually incr......
