Human beings have existed on this planet for more than 2 million years. In the long history of human beings, the discovery and application of electricity has greatly accelerated the development of human production and life. Since then, human life has been deeply bound to electricity, which has become an important material foundation of modern society.
The electrified road transportation system organically combines the efficiency of electrified railways with the flexibility of roads, and achieves compatibility and complementarity with new energy technologies. In the scenario of bulk logistics collection and distribution, it realizes the lowest cost and highest energy and resource utilization rate of the road-rail transport system solution in the whole life cycle.
Among them, the on-board DCDC product is the core component of the core carrier electrified vehicle in the system.
However, with the development of the era of electrification, the diversification of human demand for electricity has increased rapidly, bringing huge challenges and impacts to traditional power supply and control systems.
(Cut to a TV news report) Frequent problems have caused different degrees of impact on the power system, especially the outdated design of Hong Kong train circuit breakers. Traditional electrical components and electrical designs cannot keep up with the modern power safety needs.
(According to the material situation and editing needs, the backward design of the Hong Kong subway can also be included as one of the links to show the complexity and redundancy of traditional power system design)
With the development of converter products with IGBT technology as the core, human control over electricity has achieved an epochal leap.Whether it is AC/DC or high/low voltage, it has achieved high-efficiency arbitrary conversion of electrical characteristics. From then on, human beings have stood at the perspective of God to control current and electric energy.
China, as the world’s largest manufacturer of high-speed rail and new energy vehicles, has nurtured a large number of world-leading electrical and electronic control companies.
As a leader in China’s converter industry, RailMac fully masters the core technology of rail transit on-board converter systems and is a high-tech enterprise integrating product research and development, production, sales and services.
As the world leader in rail transit converters, Guangyi Converter is a first-tier supplier of many world-renowned rail transit,It has attracted many well-known train manufacturers in the world, including Alstom of France, Siemens of Germany, SBB of Switzerland, CRRC of China, etc.
RailMac products have been equipped with dozens of types of vehicles such as various types of locomotives, high-speed rail vehicles and urban rail transit, and the products are distributed in more than 30 countries and regions around the world.
The company’s products are widely used in five major fields, including railway transportation, commercial vehicles, marine engineering, ships, and mining heavy trucks. The products include main converter cabinets, auxiliary converter cabinets (including battery charger series, inverters, pressure wave controllers, etc.) and new energy power chain system solutions.
RailMac products all have independent intellectual property rights and use advanced power electronics technology to ensure high energy efficiency of the power system.
Based on many years of manufacturing experience, RailMac independently customized and developed a full set of production lines for the company, including advanced PCBA testing, cable production, module assembly and product assembly technology, to ensure the quality stability of RailMac products.
