Abstract: The invention provides a method for DC voltage measurement. First, an input DC voltage is received. A temporary disturbance signal is then added to the input DC voltage to obtain a disturbed signal, wherein an amplitude of the temporary disturbance signal is greater than precision level of an analog-to-digital converter. The disturbed signal is then converted from analog to digital with the analog-to-digital converter to obtain a plurality of samples with different values. An average value is then derived from the samples. Finally, the average value is output as a measurement value of the input DC voltage.
