IGBT Fully Controlled Hydrogen Production Power Supply

1. Energy-saving and 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. 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. 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 technology is adopted to improve the efficiency of rectifier.

5. Strong isolation, strong anti-interference ability, and the harmonic is less than 5%

6. 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.

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%.

The soft parallel system mode, under normally 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.
