China Suppliers IGBT Fully Controlled Hydrogen Production Power Supply from Leading Factory for Efficient Energy Solutions
Product Feature
1
Energy & Electricity Saving
Advanced phase-shifting full-bridge soft-switching control technology of power components is adopted to make the switch tube work in soft-switching state and reduce the loss of the switch tube. The switch tube of the inverter circuit of the transformer is a switch tube with low conduction voltage and low switching loss, and phase-shifting resonance control is adopted to realize soft switching.
2
High-Performance MOSFET
The high-performance MOSFET tube has the advantages of high efficiency, simple structure, small on-state loss, strong current turn-off ability, fast switching speed, small loss and no secondary breakdown. There is almost no loss in the process of frequent turn-on and turn-off. The power saving is 10%. With the decrease of voltage and current, the proportion of energy saving will gradually increase.
3
High-Frequency Transformer
Using high-frequency transformer, the volume is small, and the loss is generally less than 1%. The transformer loss is low. The loss of copper and iron in transformer is small. The circuit system features a reduced number of loss connection points, and the copper material is used. The power factor of high frequency power supply is high, and it is kept at 0.95.
4
Full-Wave Rectification
Full-wave rectification technology is adopted to improve the efficiency of rectifier.
5
Isolation & Anti-Interference
Strong isolation, strong anti-interference ability, and the harmonic is less than 5%.
6
Distributed Power System
Distributed high-frequency power supply system works in parallel with power modules, and adopts system current sharing, N+M redundancy and hot plug technology, so that each converter can handle less power to reduce electrical stress, which breaks the bottleneck that the output power of a single converter is not large enough, and improves the output power to tens or even hundreds of kilowatts, greatly improving the reliability of the system.
Multi-Module Parallel Structure: High-power high-frequency power supply adopts multi-module parallel structure, with RS485 control system and current sharing system, and the current sharing coefficient is within 1%.
Soft Parallel System Mode: Under normal circumstances, when one module fails, the system will automatically shut down the failed unit, and the other modules can still operate normally. The failed module can be hot-swapped and maintained, ensuring that power supply will never stop.
