Please elaborate on their function, where to use, what is the difference between the output input? The more detailed the better! Thank you!
DC is called DC
AC is called AC
Exchange to transformer
Do not use an external transformer
DC power supply is a direct current, in the oscilloscope showed a linear waveform, used in the requirements of the DC voltage and current circuit
AC power supply output is AC, oscilloscope on the sine wave, used in the requirements of constant voltage, and a certain frequency of the circuit.
Your question is not very clear, I can only ask you to ask so much
DC power supply (DC can provide a stable DC power supply for the load. DC power supply power supply are mostly AC power supply, when the AC power supply voltage or load resistance changes, the regulator DC output voltage will remain Stable. DC power supply with the electronic equipment to high precision, high stability and high reliability of the direction of the development of electronic equipment, power supply made a high demand.
AC power supply (AC) can provide a stable power supply for the load of electronic devices. Also known as AC voltage regulator. The output of the AC, a variety of electronic equipment requires a relatively stable AC power supply, especially when the computer technology applied to various fields, the use of direct power supply by the AC power grid without taking any measures can not meet the needs of the way.
