DC The voltage reduction of the DC power module is realized by PWM pulse modulation technology. The input voltage is converted into a high-frequency square wave signal, and after an inductor and a capacitor filter, the output of a stable low-voltage DC voltage is realized.
Specifically, the input voltage is switched through a switching tube to generate a high-frequency pulse signal that passes through the inductor and capacitor to become a smooth DC voltage, which is output to the load. Because the duty cycle of the pulse signal can be adjusted, the module can realize the adjustment function of the output voltage, and has the advantages of high efficiency, stability and reliability.
