Applications

1. Power semiconductor devices: such as MOSFETs, IGBTs, etc., used to achieve voltage and current conversion and control.

2. Control circuit: including drive circuit, protection circuit, and feedback circuit, used to control switch action, protect equipment, and provide feedback information.

3. Filtering circuit: used to filter out the noise generated by the switch action and ensure the stability of the output voltage.

4. Heat dissipation system: Due to the heat generated by power semiconductor devices during operation, a heat dissipation system is required to ensure their stable operation.

5. Input and Output Interface: Used to connect power supply and load to achieve energy transmission.

1. Miniaturization: With the development of new energy vehicles, the interior space is limited, so DC/DC converters need to be designed with miniaturization to save space. For example, using flat transformers and flat vertical winding coil technology can reduce volume.

2. High efficiency: In order to improve energy utilization efficiency, the efficiency of DC/DC converters needs to be continuously improved. Adopting ZVS zero voltage switching technology can reduce switching losses and noise, and improve efficiency.

3. Intelligence: With the intelligent development of automotive electronic systems, DC/DC converters also need to have more intelligent control functions, such as automatic adjustment of output voltage, overload protection, etc.

4. Modularization: In order to facilitate maintenance and upgrading, DC/DC converters tend to be designed in a modular manner, where each module can work independently or be combined for use.

1. Provide power to the power steering system, air conditioning, and other auxiliary equipment to ensure the normal operation of the vehicle.

2. Charging low-voltage batteries: A large number of electronic components and control systems on pure electric vehicles use low-voltage power sources, and DC/DC converters ensure that these devices receive sufficient power supply.

3. Replace traditional 12V generators: In some systems, DC/DC converters become the main source of power supply for high-voltage battery systems and 12V electrical loads.

In summary, the 2kW on-board DC/DC converter plays an important role in new energy vehicles, with development trends including miniaturization, high efficiency, intelligence, and modularity. It has a wide range of application scenarios, involving various auxiliary systems and electronic devices of the vehicle.
