description:

DC/DC [Chinese explanation] refers to DC to DC power supply.

DC/DC refers to the conversion of a fixed DC voltage into a variable DC voltage, also known as a DC chopper. This technology is widely used in the continuously variable transmission and control of trolley buses, subway trains, electric vehicles, and at the same time enables the above-mentioned control to achieve accelerated and fast response performance, and at the same time receives the effect of saving energy. Replacing the varistor with a DC chopper saves energy (20~30)%. The DC chopper can not only function as a voltage regulator (switching power supply), but also effectively suppress the harmonic current noise of the grid side.

The accessories are several DC-DC power supply circuits. There are more detailed circuit diagram analysis and learning tutorials in the PDF document!
