High-Frequency Litz Wire Designed for Next-Generation Solid-State Transformers
Solid-state transformers (SSTs) are revolutionizing the early 21st century power conversion equipment with more highly efficient, miniature, and intelligent power management system. Different from the conventional low frequency transformers, SST system utilizes the higher switching frequency (>kHz) and thus advanced winding conductors (have the low AC loss) need to be used.
LP Industry Solid-State Transformer Wire (SST Litz Wire) is specifically engineered for high frequency transformer windings, power electronic converters, and innovative energy applications. Our Litz wire employs many exceptionally insulated fine copper wires to be twisted together with the best optimized twisting technology. Based on the high finesse copper wire strands and the ideal twisting technique, our SST Litz wire can reduce the effects of skin effect/close effect while increasing the transformer efficiency and thermal performance.

Why Litz Wire Is Essential for Solid-State Transformers?
Higher frequencies of AC cause the current to crowd toward the surface of the usual solid conductors, leading to higher AC resistance and wasted power dissipated in heat.
Because SST systems usually use high switching frequencies, the type of conductor is important. Since Litz wire has many insulated strands, the current is spread evenly, allowing the flow of even current and reducing high frequency losses.
Key Advantages of SST Litz Wire:
Reduced AC Losses at High Frequency
Several fine enamelled copper strands help eliminate skin effect and proximity effect in solid state transformer. Thus they enable the transformer work at higher efficiency and lower temperature.
Improved Thermal Performance
The lower the AC resistance, the less heat that is generated in the transformer windings maintains continuity of operation when the power requirement is high.
Compact Transformer Design
Operation at high frequencies can enable the SST systems to reduce the size and weight of the transformers employed within the system. To gain the maximum power density without jeopardizing the electrical reliability of the transformers design can employ an optimized construction of Litz wire.
Flexible Winding Performance
The flexible structure of Litz wire enables flexible winding for compact high-frequency transformers, inductors, and power electronic components.
LP Industry SST Litz Wire Structure
Individual Enamel Insulation
Each copper strand is independently insulated to reduce circulating currents between strands.
Multi-Strand Twisting Process
Optimized twisting ensures each strand occupies different positions within the conductor cross-section, improving current distribution.
This construction makes Litz wire ideal for high-frequency transformers, resonant converters, EV charging systems, and renewable energy power electronics.
