Problems solved by technology
Therefore, two-level, three-level, or even more-level DC / DC conversion devices are generally added to the vehicle power supply system. The voltage conversion levels are many and the structure is complex, which leads to poor system stability and will affect power supply efficiency and later EMI ( Electro Magnetic Interference, electromagnetic interference), etc. will cause adverse effects

The invention provides a vehicle-mounted power system. The vehicle-mounted power system comprises a vehicle-mounted power supply, a primary voltage conversion module and a secondary voltage conversionmodule, wherein the vehicle-mounted power supply is connected with the primary voltage conversion module, the primary voltage conversion module is used for converting a voltage of the vehicle-mountedpower supply to a first voltage and is a DC / DC converter, the first voltage is smaller than the voltage of the vehicle-mounted power supply, the secondary voltage conversion module comprises a buck unit, the buck unit is connected with the primary voltage conversion module and is used for reducing the first voltage to a second voltage, particularly, the buck unit comprises a diode, a positive electrode of the diode is connected with the primary voltage conversion module, and a negative electrode of the diode is used for outputting a second voltage. In the vehicle-mounted power supply providedby the invention, the voltage of the vehicle-mounted power supply is reduced to the first voltage by arranging the monopole DC / DC converter, the first voltage is reduced to the second voltage by combining the buck unit, the first voltage and the second voltage can be compatible with a large part of power utilization devices on an automobile, and the vehicle-mounted power system is simple in structure.
Description
【Technical field】 [0001] The invention relates to the technical field of electric vehicle power supplies, in particular to a vehicle power supply system. 【Background technique】 [0002] The vehicle power supply (that is, the battery) is generally 12V or 24V, and the vehicle system generally requires a power supply voltage of 1.2V, 1.8V, 3.3V, 4.2V, 5V and other multi-level voltages. Therefore, two-level, three-level, or even more-level DC / DC conversion devices are generally added to the vehicle power supply system. The voltage conversion levels are many and the structure is complex, which leads to poor system stability and will affect power supply efficiency and later EMI ( Electro Magnetic Interference, electromagnetic interference), etc. will cause adverse effects. [0003] In view of this, it is necessary to provide a novel vehicle power supply system to overcome the above defects. 【Content of invention】 [0004] In order to achieve the above object, the present inven...
