Abstract
A method of resistance compensation for measuring output current includes the following steps: (a) providing a secondary side loop of a conversion unit, and the secondary side loop includes a sense resistor and the first line. (b) providing a control unit for controlling the conversion unit, and the control unit is coupled to the first line and the sense resistor. (c) utilizing a first current to flow through the secondary side loop to obtain a first equivalent line resistance of the first line. (d) providing a second current by the control unit flowing through a loop of the sense resistor, the first line and the control unit to obtain a second equivalent line resistance of the second line. (e) compensating the sense resistor by the control unit according to the first equivalent line resistance and the second equivalent line resistance.
