With the continuous deterioration of the global environment and the shortage of energy, reducing air pollution and dependence on petroleum energy have become more and more issues of concern to all countries. In order to reduce environmental pollution and relieve energy pressure, research on energy-saving and environmentally friendly automobiles has become an inevitable trend in the development of the automobile industry in various countries. At present, the research and production of pure electric vehicles has become a development focus of the automobile industry in various countries. A pure electric vehicle is a car that uses a high-voltage battery as a power source for energy storage. It uses a high-voltage battery as a power source for energy storage, provides electrical energy to the motor through the high-voltage battery, and drives the motor to run, thereby driving the car forward. Pure electric vehicles do not produce exhaust pollution and are almost zero emissions, which are very beneficial to environmental protection and air clean rooms. At the same time, pure electric vehicles work together with batteries and motors, which can realize energy recovery, feedback braking, and provide Energy efficiency. Generally, a pure electric battery includes two electric energy storage systems, a high-voltage power battery and a low-voltage power battery. The high-voltage power battery is mainly used to provide energy for the driving motor when the pure electric vehicle is driven, and when the vehicle is regeneratively braked, the electric energy converted into the kinetic energy of the vehicle is stored; the low-voltage power battery is used to power the low-voltage load on the vehicle. In order to provide energy for low-voltage power batteries and low-voltage electric loads of vehicles, pure electric vehicles generally adopt a DC-DC Convert between the high-voltage power battery network and the low-voltage power battery network. In general pure electric vehicles, the DC high and low voltage converter inputs high voltage DC from the high voltage battery, and then outputs it to the low voltage battery and load in the form of low voltage. The output voltage is required to match the low voltage battery.
