TDK provides unique DC-DC conversion solutions for hybrid vehicles
In order to achieve differentiation in car design, a short-term trend is that systems that communicate with the outside world will be integrated into low-end models, such as car navigation, GPS, and automatic car toll collection system (ETC). The market for these communication systems will develop rapidly and their costs will be further reduced. The long-term trend in automotive design is to reduce energy consumption, but this requires very high costs.
In the new car design, in order to provide security, self-identification systems represented by smart key systems and smart car license plate recognition systems will also be adopted. These systems not only help to avoid the loss of vehicles, but also help to adopt multiple external communication functions. When designing these systems, software technology is the key technology to avoid the invasion of viruses, but these technologies have been applied in the field of information appliances; hardware requirements are to adopt technologies that can achieve higher speeds and larger transmission capacities.
In the long run, a key trend in automotive design is to reduce energy consumption. Hybrid electric vehicles (HEV) will become the current alternative to traditional vehicles. Compared with traditional cars, HEV's automotive powertrain requires more electrical management systems. In HEV, the cost of electronic components is close to half of the cost of the entire vehicle, and in the current traditional cars, the cost of electronic components accounts for about 20% of the cost of the entire vehicle.
HEV has two important characteristics: one is long battery life, high stability and high efficiency; the other is high efficiency of energy transmission (reduction of energy loss). This requires the use of smaller, lighter multi-function control units. From the perspective of environmental protection, the control unit itself also requires the use of harmless materials. In other words, designs that reduce energy consumption must require higher efficiency and smaller, lighter control units. In addition, various noises between the wiring harness and the control unit must be EMI-suppressed because the number of high-current, high-voltage, and high-frequency control units in HEVs is greater than in conventional vehicles.
TDK launched a DC / DC converter with high efficiency, smaller size and lighter weight for the Japanese HEV market. By changing the aluminum package to a resin package and using the best circuit structure, TDK reduced the weight of the DC / DC converter by 45%, the volume by 5%, and the total weight of less than 1 kg. Technology in raw materials is an important advantage of TDK, which can increase the value of circuit technology. In addition, taking advantage of the latest developments in raw materials, TDK can provide customers with better solutions based on their extensive experience in the automotive field.
