Electrolytic Cell Power Supply Device with Corrosion Prevention
Solution Overview
Problem
Existing electrolytic cell power supply devices face challenges in suppressing the generation of reverse currents during power interruptions, leading to degradation of the electrolytic cell, and require a complex configuration with additional components like separate corrosion prevention power supplies.
Innovation Solution
An electrolytic cell power supply device is designed with a first converter to convert AC power to DC, a storage element to store DC power, a second converter to adjust the DC power for the electrolytic cell, and a control device that switches between normal and corrosion prevention modes to manage power supply and prevent reverse currents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate corrosion prevention power supply is prepared, then the generation of reverse current is suppressed, but the number of components is increased and equipment configuration becomes complex
Solution Approach 1:
The patent merges the corrosion prevention function into the existing power supply device by incorporating a storage element and control device that can operate in a corrosion prevention mode. This eliminates the need for a separate corrosion prevention power supply while maintaining the ability to suppress reverse current during power interruptions.
Solution Approach 2:
The power supply device is designed to perform multiple functions: normal power supply operation and corrosion prevention operation. The control device can switch between these modes, allowing the same hardware to serve both primary power supply and protective functions during outages, thereby reducing overall system complexity.
2Reliability
If a separate corrosion prevention power supply is prepared, then the generation of reverse current is suppressed, but equipment costs increase
Solution Approach 1:
The patent combines the corrosion prevention functionality with the existing power supply device, eliminating the need to purchase, install, and maintain a separate power supply system. This integration reduces overall equipment costs while maintaining protective capabilities.
Solution Approach 2:
The power supply device is designed to protect itself during outages by using its own storage element to provide corrective current. The system serves its protective function without requiring external separate equipment, thereby reducing total system cost.
