The hydrogen production power supply adopts high-frequency IGBT fully controlled power devices and PWM control technology, which has outstanding advantages in power response speed, voltage ripple, comprehensive efficiency, etc., and is more suitable for large-scale new energy hydrogen production scenarios. IGBT is an insulated gate bipolar transistor with the characteristics of high voltage resistance, low conduction voltage, and fast switching speed.
This hydrogen production power supply has constant voltage and stable current output control function, as well as local/remote communication control function. The system protection function is complete, and the main controller adopts the fourth generation thyristor trigger board independently developed by our company, with high adjustment and control accuracy and good symmetry of positive and negative pulses. The system has complete protection functions, strong anti-interference ability, and high reliability. Simple operation, user-friendly design, high degree of automation, power supply design and manufacturing follow IEC international electrical technical standards and national industry technical standards.
1. High stability: Advanced technology, imported core components, strict quality control, and improved protection functions comprehensively enhance product stability.
2. High precision control: The output control accuracy can reach 1% throughout the entire process.
3. Good energy-saving effect: Low voltage thyristor reduces the efficiency of the rectifier power supply.
4. Complete protection function: with input phase loss, overvoltage, and undervoltage; Output current limiting and voltage limiting protection, providing comprehensive protection for equipment.
5. The rectifier transformer made of high-quality oriented and high magnetic density imported silicon steel sheets has higher efficiency.
6. Advanced cooling design concept, multiple cooling methods complement each other, ensuring the high efficiency and stability of the product.
7. Fully digital design for more precise control. Supports bus control and can form a central control power supply system, facilitating management and improving efficiency.
8. The use of 12 phase rectification can effectively reduce the generation of 5th, 7th, and 9th harmonics and interference with the power grid.
