Customized Stacked BusBar
Busbar designs can be customized to meet customer needs in terms of the number of layers, width, thickness, and insulation method to match different power ratings and installation spaces. Whether it's a small server power supply or a large industrial frequency converter, it achieves a compact layout and efficient energy transfer.
Manufacturing Process: Military-Grade Precision Composite Process
Material Micro-Modification: The copper plate edges undergo comprehensive rounding and passivation (R-corner micro-machining) to eliminate sharp corners and prevent localized electric field concentration under high voltage.
Surface Cleaning: Precision chemical cleaning removes trace oxides from the copper surface, enhancing adhesion to the insulating film.
Laminated Layout and Precision Assembly: Multiple conductors and insulating films are precisely aligned and laid in a Class 10,000 cleanroom environment.
Multi-Segment Vacuum Hot Pressing: This core process achieves physical-level dense integration through precise control of heating, heat preservation, pressurization, and cooling rates.
Edge Sealing and Moisture-Proof Coating: The partially laminated bus bar edges undergo secondary injection molding sealing or special insulating varnish coating to prevent external moisture intrusion.
Factory electrical stress full inspection: high voltage withstand voltage test (Hi-Pot Test), partial discharge test (PD Test), and insulation resistance test are performed.
Detailed Showcase: Witnessing Rigorous Engineering in the Tiniest Details
Edge Insulation Transition
Observing the Three-layer laminated busbar edges, the insulation coating evenly and smoothly covers the copper layer, forming a seamless R-corner transition with no exposed copper. This effectively prevents electric field concentration at sharp angles, eliminating surface discharge.
End Face Flatness and Coplanarity
The mounting end faces after multilayer lamination have extremely high coplanarity, with no warping or steps. This ensures absolutely uniform stress during pressing with the IGBT module base plate, avoiding single-point overheating and melting due to poor local contact.
Bubble-Free Insulation Layer Visibility
Under strong light, the insulation medium is as pure as crystal, without any tiny bubbles or impurities. This is a physical guarantee of near-zero partial discharge and a direct manifestation of resistance to heat aging.
Precision positioning holes and foolproof markings
Each mounting hole and positioning pin hole has a precise chamfer, and the surface is printed with clear phase sequence markings and barcode traceability information to ensure zero error rate in high-voltage assembly on site.
Main functions and system value
Low impedance feed
The energy stored in the DC support capacitor is delivered to the P and N terminals of the IGBT module with extremely low resistance and inductance to ensure that the voltage drop during the switching process is minimized.
01
Absorb high-frequency ripple
Its own interlayer distributed capacitance (usually tens to hundreds of pF) can act as a high-frequency filter capacitor, absorbing the switching ripple from the inverter and improving the DC bus voltage quality.
02
Electromagnetic shielding and low EMI
The laminated structure naturally forms a nearly complete shielding surface, which greatly reduces radiation interference and helps the whole machine pass the electromagnetic compatibility test.
03
Power integration interfaceA
laminated busbar in High Power Converter can be used as a structural component to simultaneously fix the IGBT, capacitor, driver board, and temperature sensor, simplifying the assembly process and improving earthquake resistance.
