China IGBT Fully Controlled Hydrogen Production Power Supply - Leading Suppliers and Factory Solutions

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.

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.

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.

Full-wave rectification technology is adopted to improve the efficiency of rectifier.

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

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.
