Problems solved by technology

Usually, the composition of a DC stabilized power supply includes: a power transformer, a rectifier, a filter, and a voltage stabilizer. The function of the transformer is to transform (usually step down) and isolate; the function of the rectifier circuit is to convert AC power into pulsating DC power; The function of the filter circuit is to filter out the AC components in the pulsating DC as much as possible to make the output voltage smooth; the function of the voltage regulator circuit is to stabilize the output voltage, that is, when the power supply voltage, load and ambient temperature change within a certain range, The voltage stabilizing circuit can automatically adjust to keep the output DC voltage basically unchanged. In the traditional method, the output DC power fluctuates greatly and is relatively single.
