South Korea’s offshore floating PV project presented an array of technical challenges due to its high-salinity, high-humidity, and corrosive marine environment. To ensure high reliability, durability, and protection levels for core power conversion components, LJ-MD delivered a series of breakthrough technologies backed by multiple patents:

1. High-Performance Anti-Reverse Diodes

One of LJ-MD’s core innovations, this diode series features:

• Optimized structural design: enhanced heat-dissipating substrates and sealed enclosures;

• Advanced material processes: corrosion-resistant alloy leads and anti-salt-mist coatings;

• IP68-level protection and stable operation in hot, humid, salt-heavy environments.

The product is protected by the core patent “Anti-Reverse Diode for High-Humidity Salt-Mist Environments and Its Manufacturing Method”, which ensures reliable performance on the DC side of offshore PV systems—resolving a critical safety risk.

2. High-Reliability Three-Phase Rectifier Modules

Designed for limited offshore platform space and complex heat dissipation conditions, the modules feature:

• Integrated cooling and compact structure design, patented by LJ-MD;

• Special encapsulation and thermal management materials for efficient heat flow;

• “Single-row screw” installation design, simplifying setup and improving field reliability.

3. Custom-Tailored Engineering Solutions

LJ-MD didn’t offer one-size-fits-all products. Instead, it delivered highly customized solutions based on deep insights into project-specific operating conditions. For example:

• Special anti-corrosion treatments were applied at critical joints;

• Devices were enhanced with higher surge-withstand capabilities (I²t rating) for ocean-induced power fluctuations.

These innovations were crucial to the stable, efficient, and safe operation of the offshore PV plant, and were key reasons LJ-MD’s solutions stood out to the SNEC jury.
