Laminated Busbar For High-Current Power Electronics
Products Description
Laminated Busbar for High-Current Power Electronics are integrated conductor assembly formed by a hot-pressing composite process using multiple layers of conductive materials (copper/aluminum) and high-performance insulating media. Unlike traditional discrete wiring, their core features are:
Planar multilayer structure design: minimizing current paths
Tight coupling between conductors: significantly reducing parasitic inductance
Integrated insulation layer: improving system insulation reliability
For UPS systems, this product focuses on optimizing the following structures:
Symmetrical layout of input/output circuits
High-density terminal integration design
Multi-interface modular structure compatibility
Manufacturing Advantages and Production Processes: Meticulous Craftsmanship Standards
Digital CNC Machining and Pre-treatment
Conductor Integrated Laminated Busbar Cell Contact Systems are cut using high-precision CNC machining or continuous stamping, with edges rounded to eliminate the risk of localized point discharge (PD). Multiple chemical cleaning processes are then performed to ensure the interface is free of grease and oxidation.
Vacuum High-Temperature Lamination
This is the core of the process. In a vacuum hot press, the "pressure-temperature-time" curve is precisely controlled to achieve physical bonding between the insulation material and the conductor at the molecular level. The vacuum environment eliminates interlayer air, effectively preventing corona discharge caused by residual air.
Localized Coating and Electroplating
Contact points are typically plated with nickel, tin, or silver. We employ a localized electroplating process, ensuring low contact resistance and oxidation resistance at the connection points while maintaining the integrity of the insulation coating in non-connection areas.
In-depth Analysis of Key Functions and Application Scenarios
UPS Uninterruptible Power Supply (Core Application)
In large data center UPS systems, the Laminated Power Bars connect battery packs, rectifiers, and inverters. Its high reliability ensures "zero-interruption" operation of the data center; its low inductance characteristics protect expensive IGBT power modules from voltage breakdown; and its compact structure helps customers significantly save data center space.
Server Power Supply and Communication Power Supply
In board-level power supply design, the Laminated Busbar for Rail Traffic acts as a power bridge between the daughterboard and the motherboard, providing an extremely low impedance path, supporting the instantaneous power response of high-performance chips such as processors, and ensuring voltage stability.
New Energy Converters and Drivers
In photovoltaic inverters and frequency converters, the Laminated Busbar for High-Current Power Electronics withstands the heat and electromagnetic stress generated by high-frequency switching, and its current-sharing characteristics effectively improve system efficiency.
