Typical application cases and core feature analysis of Laminated busbar for electric car

Industrial frequency converter busbar is an electrical connection component with a multi-layer composite structure. With core advantages such as low inductance, low impedance, anti-interference, high reliability, and compact structure, it is widely used in small, medium, and high-power converter applications and has become an indispensable key component for the development of the power industry. Compared with traditional bulky and cumbersome wiring methods, Laminated copper busbars can achieve modular and simplified design of power distribution systems, with characteristics such as easy design, fast installation, clear structure, and repeatable electrical performance. Like the "highway" of power distribution systems, they effectively improve the efficiency and stability of power transmission, and are suitable for power conversion and transmission needs in multiple fields such as photovoltaics, wind power, frequency converters, rectification devices, etc.

The widespread application of Laminated copper bars stems from their multiple advantages of economy and practicality, among which the most prominent core advantage is the low inductance characteristic, which is a key highlight that traditional busbars cannot replace. For IGBT and other switching devices, low inductance can effectively avoid device breakdown caused by surge voltage, ensuring the safe and stable operation of power systems.

In addition, the Laminated bus bar for industrial also has ten core advantages: low overall cost, which can achieve maximum cost-effectiveness; Outstanding reliability and safety, reducing operational hazards in the power system; A simple and compact design can greatly save installation space and adapt to various compact working conditions; Low impedance characteristics reduce power transmission losses; It can significantly reduce the probability of installation errors and improve assembly efficiency; Convenient on-site installation and post service, reducing operation and maintenance costs; The increased branch capacitance can optimize electrical performance; Compared with traditional cables, under the same conditions, the download capacity is significantly improved, and the temperature rise is lower under the same current carrying conditions, further extending the service life of the equipment.

In the main power circuit, the parasitic inductance of switch devices and DC side capacitors is usually difficult to change, and the fundamental measure to suppress switch voltage spikes and improve system stability is to reduce the distributed inductance of the main circuit bus. At present, there are four main forms of electrical connection between DC side supporting capacitors and switching devices, among which Busbar for electric locomotive has particularly significant performance advantages.

Parallel arranged copper bars or plates are easy to produce and have a low cost. They have a certain suppression effect on voltage spikes, but they have a large mutual inductance and are only suitable for situations with high power and low performance requirements; Cable stranded wires are cheap and easy to use, but they have high self inductance and mutual inductance, limited current carrying capacity, and are suitable for low-power and low performance scenarios; Coaxial cables have small mutual inductance and are easy to use, but they are expensive and have insufficient current carrying capacity, making them suitable for low-power and medium performance requirements.

The Laminated bus bar for telecom is formed by stacking multiple layers of copper bars, isolating and compressing them into a whole through interlayer insulation. The flat cross-section increases the conductive surface area and reduces the interlayer spacing. By utilizing the proximity effect, the magnetic fields of the reverse currents in adjacent conductive layers cancel each other out, greatly reducing the distributed inductance, while increasing the heat dissipation area and improving the current carrying capacity. Its comprehensive performance far exceeds traditional connection methods.

Relying on its excellent comprehensive performance, the application scenarios of Motor controller busbar have comprehensively covered multiple fields, including core links such as power transmission and power conversion.

In the field of new energy, power conversion modules are widely used in photovoltaic and wind power systems to achieve efficient transmission and conversion of electrical energy and adapt to complex outdoor working conditions.

In the industrial field, various types of frequency converters, rectification devices, electric braking units, electric traction equipment, and welding systems have their presence, effectively improving equipment operating efficiency and stability.

In the field of electronic communication, Laminated bus bar for variable frequency drive is suitable for cellular communication base stations, telephone exchange systems, large network equipment, large and medium-sized computers, etc., ensuring stable transmission of signals and power.

In addition, it can also be applied to military equipment systems, power generation systems, electric equipment power conversion modules and other scenarios, fully meeting the power transmission and connection needs of different fields.
