For a long time, the management of substation batteries was essentially a "periodic task."It involved measuring internal resistance once a year, conducting periodic capacity verification discharges, checking that float-charge voltages were within normal ranges, and recording the data in a log. For m...... READ MORE
—Rethinking Current Sensing Systems in the MLPE EraForeword: What is becoming increasingly difficult is not the inverter itself, but the "sampling."In recent years, micro-inverters have been regarded as the quintessential MLPE (Module-Level Power Electronics) solution for residential photovoltaic sy......

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......
