Abstract
A primary-controller with voltage compensation function applied to a primary side of a power converter includes a gate control signal generation circuit, and the gate control signal generation circuit includes a clamping unit and a driving unit. The gate control signal generation circuit is coupled to a power switch installed in the primary side of the power converter, and is used for enabling a gate control signal, wherein the gate control signal is used for making the power switch turned on. The clamping unit generates a compensation voltage according to a clamping voltage. The driving unit is coupled between the clamping unit and a gate of the power switch, and used for generating the gate control signal according to the compensation voltage. The clamping voltage is changed with a detection voltage of a detection resistor coupled to the power switch accordingly.
