Foreword: A frequency converter is a device that outputs any desired frequency value. Frequency conversion is usually implemented in an AC-DC-AC manner. Voltage and current sensors are an important "sensing organ" function in a frequency converter. They can monitor and feedback key parameters in rea...... READ MORE

In the pursuit of the "double carbon" goal, wind energy is one of the main forces of clean energy, and its stable and efficient operation is directly related to the security of energy supply and power grid. Inside this behemoth, the precise "sensory nervous system" is silently guarding the smooth tr...... READ MORE

In modern railway transportation, whether it is the "Fuxing" high-speed rail with a speed of 350 kilometers per hour or the "Harmony" high-speed train with a speed of 250 kilometers per hour, it is mainly driven by electricity. The locomotive traction system is the core power system to ensure the ef...... READ MORE

In recent years, the global energy storage market has shown explosive growth. According to relevant data, the new installed capacity of global energy storage in 2024 is about 175.4 GWh, and it is expected that the new capacity will reach 247 GWh in 2025, an increase of 35% year-on-year. However, wit...... READ MORE

In recent years, especially in 2025, the photovoltaic industry is facing challenges such as overcapacity, price wars, and homogeneous competition. Crystalline silicon prices have repeatedly hit new lows, module prices have fallen to 0.7 yuan per watt, and corporate profit margins have been compresse...... READ MORE

As we all know, "double carbon" refers to "peak carbon dioxide emissions" and "carbon neutrality". In the "double carbon" strategy, our country's photovoltaic power generation plays a main role. According to the data of the National Energy Administration, in the first half of this year, the new inst...... READ MORE
