» Types of electroplating

› Copper Plating

Purpose: Enhances adhesion for subsequent layers and corrosion resistance.

Note: Prone to oxidation (forms non-conductive copper oxide/green patina). Requires protective coatings.

​› Nickel Plating

Purpose: Used as a base layer or decorative finish; improves corrosion/wear resistance. Electroless nickel offers chrome-like durability.

Note: Magnetic properties limit use in electronics (e.g., DIN/N connectors) to avoid signal interference.

​› Gold Plating

Purpose: Optimizes conductive contact impedance and signal transmission.

Key: High stability but costly.

​› Palladium-Nickel Plating

Purpose: Superior signal transmission and wear resistance vs. gold.

Advantage: Combines palladium’s corrosion resistance with nickel’s hardness.

​› Tin-Lead Plating

Purpose: Improves solderability.

Trend: Phased out due to lead concerns; replaced by bright/matte tin alternatives.

​› Silver Plating

Purpose: Best conductivity and signal performance.

Note: Conducts even when oxidized but tarnishes over time. Higher cost.

​Selection Criteria

Match plating type to application needs: corrosion/wear resistance, conductivity, cost, and environmental regulations.

» Elements of Electroplating

› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.

› Anode

​Soluble Anode: Made of the plating metal. Dissolves during electrolysis to replenish metal ions in the solution.

​Insoluble Anode: Used for precious metals (e.g., white gold, iridium oxide). Does not dissolve but supplies electrons for reduction.

› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.

› Plating Tank

Materials: Must resist corrosion and temperature fluctuations (e.g., polypropylene, titanium alloys).

Role: Stores solution and maintains stable plating conditions.

› Rectifier

Converts AC to DC power to drive electrolysis.

Adjust voltage/current to control deposition speed and coating thickness.

› Auxiliary Equipment

​Filters: Remove impurities from the solution.

​Heaters: Maintain solution temperature.

Hydrogen Electrolysis Rectifier: Powering Green Hydrogen Production.​

The ​Hydrogen Electrolysis Rectifier​ provides the necessary DC power for the electrolysis process and is the essential power supply equipment for hydrogen production from electrolytic water. Its reliability is crucial to the reliable and stable operation of the ​electrolyzer.

After the AC input voltage is filtered by the rectifier circuit, the high-voltage DC power is obtained. “Variable frequency conversion” can invert the high-voltage direct current into about 30 kHz high-frequency alternating current, which is then converted into the secondary voltage by a high-frequency transformer, and then filtered by the high-frequency rectifier circuit to obtain the required output voltage ​for hydrogen electrolysis.

Then, sampling of the output voltage and current is performed by the control circuit, and the signal of pulse width modulation (PWM) for controlling the inverter circuit is generated after closed-loop feedback to keep steady output voltage and current ​for hydrogen electrolysis.

Application of Hydrogen Electrolysis in Hydrogen Energy

Among various hydrogen-production methods, ​Hydrogen Electrolysis​ is widely used. The ​Power Rectifier​ primarily supplies DC power for the electrolysis reaction, producing hydrogen and oxygen from water.

The generated hydrogen has broad applications—refineries, fuel cells, ammonia/methanol synthesis, metal processing, food production, and electronics—with especial prominence in the vehicle industry.

Hydrogen Electrolysis​ is achieved by linking a ​Power Rectifier​ to the conventional power grid and coupling it with an electrolyzer. Alternatively, renewable sources (photovoltaic, wind, wave, biomass—termed ​Green Hydrogen​ when derived renewably) can also power the rectifier-electrolyzer system. An inverter mediates between hydrogen storage and the grid.

Core Advantage of Hydrogen Electrolysis

High efficiency, high regulation accuracy and stable output

The rectifier adopts multiple modules in parallel, with a small single module, low requirements for electronic components and low failure rate.

Multiple protection

The power supply has multiple protection functions such as overcurrent, phase loss, and over temperature.

Anti-corrosion, beautiful and long service life

The high-power rectifier basically overcomes the influence of eddy current heating of the large current magnetic field, so the loss is small and the service life is long.

Convenient installation

The circuit of the busbar is short, and the number of supporting points and joints of the busbar is small. Therefore, the installation is simple and convenient. During installation, construction personnel only need to stand on the concrete foundation platform to complete the installation of the power supply and busbar, without the need for scaffolding, and there is no risk of working at heights for construction personnel.
