The Electrophoretic Rectifier‘s innovative cabinet structure retains all advantages of non-co-phase inverse parallel configurations while introducing critical technical advancements. This design addresses evolving demands in the electrolytic aluminum industry—particularly high-voltage serial applications—while resolving limitations of traditional vertical (co-phase inverse parallel) architectures. Enhanced safety coefficients surpass conventional systems, coupled with reduced failure rates and simplified maintenance protocols.

» Product Applications

The Electrophoretic Rectifier and Plating Rectifier Equipment series are extensively utilized for a wide range of surface treatment applications, delivering precision, efficiency, and reliability. These rectifiers are particularly well-suited for processes such as PCB electroplating, hard chrome coating, and plating with metals like copper, nickel, zinc, gold, and silver. The Rectifier ensures consistent and high-quality results in these applications by providing stable voltage and current control, which is essential for achieving uniform coating thickness and enhanced surface properties.

» Technology Advantages

Select thyristors with low on-state threshold voltage: thereby reducing power consumption and improving rectification efficiency. Analysis of rectifier cabinet losses reveals that thyristor losses constitute a significant proportion of the total cabinet losses, with the on-state threshold voltage exerting a notable impact on device losses. It is recommended to select thyristor models with a low on-state threshold voltage and stable, reliable performance.Regarding the parallel design of rectifier bridge arms, inherent variations in thyristor characteristics result in discrepancies in the on-state threshold voltages of individual components. This leads to uneven current distribution among parallel branches. To mitigate this, the number of parallel components should be minimized while ensuring current-carrying requirements are met.

The more parallel elements, the greater the conductive imbalance. Therefore, try to select thyristors with large forward average current, reduce the number of parallel elements in the rectifier bridge arm, and improve the current sharing coefficient of the rectifier bridge arm.
Use current-sharing reactors for forced current sharing: Between the two thyristors in the same bridge arm, a low-power current-sharing reactor developed by our company is added for forced current sharing. The current-sharing coefficient is as high as 0.96 or above (when the current-sharing reactor is not used, the current-sharing coefficient is 0.85~0.88), which improves the rectification efficiency.

Non-ferrous metal electrolysis, such as copper, zinc and aluminum electrolytic.

» Role of Electrophoretic

The electrophoretic rectifier serves as the operational backbone of modern surface treatment systems, delivering voltage regulation within ±0.5% tolerance and current stability below 1% ripple. This precision enables uniform metal deposition critical for functional coatings – automotive electroplating achieves 8-12μm chromium layers with 1,200 HV hardness, while PCB copper plating maintains ±0.8μm thickness consistency across 24-hour production cycles.

» Types of Electrophoretic

By Current Regulation Technology

• Thyristor-SCR Units: Phase-controlled DC output (0-24V/1,000-50,000A), ±2% ripple for bulk electroplating lines
• IGBT Modular Systems: High-frequency switching (5-20kHz), ±0.5% stability for precision anodization (e.g., automotive Al wheels)
• Pulse Rectifiers: Adjustable ton/toff (0.1-100ms) for nanostructured coatings (Ni-PTFE composites)

Application-Specific Configurations

• Electrolytic Refining: Current density control (3,000-15,000 A/m²) for Cu/Zn/Ni electrowinning cells
• Hybrid Systems: Voltage-current dual mode switching for combined electroplating/passivation cycles

Performance Benchmarks

• Efficiency: 92-96% conversion (IGBT vs. 80-85% SCR)
• Current Sharing: <2% deviation across 8+ parallel baths (automotive E-coat lines)
• Waveform Control: Programmable ripple <1% for medical implant coatings

Industry Implementation

• Automotive: 600V/10kA units for body E-coating (18-22μm uniformity)
• Electronics: 50V/5kA precision rectifiers for Au/Ni PCB edge connectors
• Energy: 1,200VDC systems for Zn-Ni battery foil production

Structural Rationale: Maintains technical hierarchy while embedding operational parameters and industry-specific validation metrics.

The Anodizing Rectifier delivers precise high-voltage control (up to 120V+) for hard anodizing while seamlessly supporting 25V DC/AC coloring applications, bridging both functional and decorative processes. Engineered for extreme scalability, it accommodates currents ranging from hundreds of amps to 12KA outputs, ensuring robust performance for large-scale industrial demands. Its high-frequency switching technology slashes oxide layer formation time by 30% compared to conventional rectifiers, while cutting energy consumption across operations—whether for aerospace-grade hard coatings or intricate DC/AC coloring of architectural components.

The compact, modular design guarantees ±1% voltage stability even at 25V precision levels, critical for achieving flawless color consistency in dyed finishes. This stability, combined with 12KA current capacity, enables uniform Al₂O₃ films for corrosion-resistant surfaces and repeatable results in high-stakes sectors. Post-treatments like hot-water sealing integrate effortlessly, with the DC/AC mode enhancing dye adsorption and minimizing color banding. By merging ultra-hard anodizing capabilities with 25V-12KA coloring versatility, the system reduces footprint, downtime, and operational costs—ideal for manufacturers transitioning between protective coatings and decorative finishes within a single streamlined setup.

» Product Applications

Anodizing Rectifier drives the electrochemical formation of aluminum’s oxide layer (Al₂O₃), critical for industrial applications demanding corrosion resistance and structural integrity. By delivering stable current outputs, it enables uniform growth of protective coatings with adjustable thickness (5–25μm), essential for automotive trim exposed to road salts or marine-grade architectural window frames. The technology ensures surfaces achieve 500–900 HV hardness for scratch-resistant smartphone casings while maintaining dielectric properties for heat sink insulation in 5G equipment. Post-anodizing, the rectifier-compatible sealing process locks in organic dyes for fade-resistant facade panels and medical device markings. Its adaptive voltage control (12–120V DC) supports both Type II decorative finishes on consumer electronics and Type III hard coatings for aircraft landing gear components, achieving 60% faster cycle times versus traditional rectifiers through pulsed current optimization.
