the popularization of intelligent transportation systems, intelligent vehicle
terminal has emerged. As the most important part of the Intelligent
Transportation System (ITS), the smart vehicle-mounted terminal integrates
technologies such as the Internet of Things, satellite navigation technology,
and even artificial intelligence, and is now widely used in various modes of
transportation. The output voltage of automotive vehicle power supplies is
generally 12 V, 24 V, 36 V, while the operating
voltage of embedded chips inside vehicle-mounted terminals such as automobiles
or buses generally needs to be depressurized before they can work normally.
Therefore, this paper will analyze four basic DC chopper circuits, analyze its
working principle, and build a DC-DC circuit model according to Matlab/Simulink
software and finally analyze the waveform of the simulation output.
