Abstract
A method for obtaining electric power information is applied with a power supply and includes following steps of coupling the power supply to an AC power source; detecting a voltage of the AC power source to obtain a first voltage; detecting a frequency of the AC power source to obtain a first frequency; and estimating an electric power information of the power supply in accordance with the first voltage and the first frequency. The electric power information includes an input current, an input voltage or an input power outputted from the AC power source to the power supply.
