Abstract: An off-line non-step adjustment voltage regulator. The inventive voltage regulator employs a high frequency switch mode to perform the electricity transformation in a converter, and employs an appropriate micro-processing control to couple the energy of the converter to an output end via a transformer so as to form a serial increasing/decreasing effect. Then, an output voltage is output, and is sent to a control circuit. The output voltage will be compared with a reference value so as to control the stability of the output voltage. Therefore, the invention can achieve the objective of performing efficiently, saving energy and precise non-section adjustment voltage regulation so as to reduce the system cost. Furthermore, the inventive voltage regulator is suitable to each stage of the voltage regulation equipments with different capacities.
