Abstract:
A power supply with a mixed regulator, comprising:a power source transferring circuit transferring an AC power source to a DC power source; a switching mode voltage circuit (14) having multiple inputs and outputs, wherein each of the inputs connects to an output of the power source transferring circuit and an output of the switching mode voltage circuit (14) is an output of the power supply to output a low voltage of the DC power; a series pass controlling circuit (15) connected to an output of the switching mode voltage circuit (14) to detect an output changing and adjust the output DC power according to the output changing; and a controller (16) connected to the input of the switching mode voltage circuit (14) and the input of the series pass controlling circuit (15), wherein outputs of the controller (16) are connected to the output of the switching mode voltage circuit (14) for obtaining a sampling output voltage and sampling current to adjust a frequency of the output DC power source to be the same as the input AC power source.
