[0002] A Buck chopper power supply is a device that converts a fixed DC voltage into a variable DC voltage; it is also known as a DC pulse width modulation (PWM) or frequency modulation system. Its core function is to change the output voltage by adjusting the pulse width or frequency to meet the needs of different applications.
