Electrocatalytic Oxidation Rectifier – 48V 1000A Digital IGBT Power Supply by GAOHUI

Executive Summary
Standard industrial rectifiers waste up to 30% of input energy through heat dissipation and poor voltage regulation, undermining the operational economics of electro-Fenton advanced oxidation systems and large-scale COD removal processes. GAOHUI engineered this 48V 1000A power supply specifically to solve the brutal energy demands of electrocatalytic oxidation, where current stability directly dictates radical generation efficiency and electrode lifespan. This system delivers a stiff 48-kilowatt output with >92% efficiency, built for continuous duty cycles in industrial effluent treatment plants.
Part 1 Key Features & Engineering Highlights
This unit integrates soft-switching IGBT topology with a fully digital PID control loop, enabling millisecond-level response to load impedance changes caused by variable conductivity wastewater. The core architecture is sourced from a dedicated industrial high frequency rectifier factory, ensuring high-density packaging that reduces floor space by 40% compared to SCR-based predecessors. An integrated PLC interface allows the rectifier to receive real-time setpoints from a DCS, adapting the current density on-the-fly as contaminant concentration drops. The heavy-duty copper busbars and dual-stage EMI filters are standard, making this unit suitable for operation near sensitive analytical instrumentation.

Part 3 Advanced Built-in Protection Systems
Electrocatalytic oxidation cells are sensitive to polarity reversal and overvoltage spikes. This rectifier includes: primary input overvoltage / undervoltage lockout, output short-circuit protection that clears within 5 microseconds, phase-loss detection for three-phase input, and automatic derating on high internal heatsink temperature (85°C threshold). A dedicated ground-fault interrupter monitors leakage current, shutting down the DC bus if it exceeds 30mA to protect operator safety. The system logs the last 100 fault events with timestamps.
Part 4 Target Industrial Applications
This unit excels in the following demanding electrochemical processes:
– Electro-Fenton advanced oxidation for recalcitrant COD removal in pharmaceutical and chemical wastewater.
– Industrial effluent treatment for textile dyeing and landfill leachate where color and toxicity must be neutralized.
– Heavy-metal electrowinning and recovery from spent process baths.
– Anodic oxidation of refractory organics in large-scale detoxification projects.
Part 5 Customization and Tailored Engineering Services
GAOHUI operates as a specialized custom current voltage rectifier developer, offering deep modification beyond standard catalog items. For this 48V 1000A platform, we can integrate: a Process Timer for scheduled batch operations, Multi-Stage Profile Control for stepwise ramping of current to condition electrodes, an Ampere-Minute Integrator to track total charge passed for precise reaction termination, and Automatic Reverse Polarity switching (0.1 sec to 99 hours cycle) for electrode cleaning. Digital interfaces include RS485 Modbus RTU, Ethernet TCP/IP, and an isolated 4-20mA analog input for remote setpoint following. An optional Pulse Function module delivers square-wave pulses from 1Hz to 3000Hz adjustable duty cycle (10%-90%), dramatically improving mass transfer in non-conductive wastewater. Minimum custom voltage of 1V, maximum 1000V; minimum current 1A, maximum 100,000A. Input AC only, output DC only.
