1. The cycle characteristics are different.
The magnitude and direction of the current of the AC regulated power supply will change periodically with time. There is no periodic change in the DC regulated power supply.
2, the composition structure is different.
The AC stabilized power supply consists of an input switch, a voltage regulator, a sampling circuit, a drive device, an output protection device, a control circuit, and a display. The DC stabilized power supply is composed of a power transformer, a rectifier filter circuit, a filter circuit and a voltage stabilizer circuit.
3, the conversion method is different.
The AC regulated power supply is converted into a DC regulated power supply through rectification + filtering to obtain pulsating DC power. The conversion of DC regulated power supply into AC regulated power supply is to obtain various sine wave AC power through oscillation inversion.
