Abstract

A saved power measuring circuit comprises a control unit, a clock signal generating circuit connected to the control unit for generating a clock signal to the control unit, a power consumption measuring circuit connected to a power supply loop for measuring the power consumption of an electric appliance load operated in operation mode, a power consumption memory unit connected to the control unit for memorizing the power consumption, a break loop status signal generating circuit for generating a break loop status signal to the control unit. When the control unit receives the break loop status signal generated from the break loop status signal generating circuit, it calculates saved power of the electric appliance load in power saving mode according to the power consumption and the lasting time after receiving the break loop status signal.
