A compensation control circuit is provided, which may be connected to a converter to compensate its error. The compensation control circuit may include a compensation control module, a control module and a modulation module. The compensation control module may include a compensation control port, and the compensation control module can receive a compensation database via the compensation control port and then output a compensation signal corresponding to the compensation database. The compensation database can be created by pre-measurement, which may include the compensation signal corresponding to the error that will occur on the converter under a specific input power signal. The control module can output a control signal according to the compensation signal. The modulation module can modulate the control signal into a modulation signal and output the modulation signal to the converter so as to control the output signal of the converter.
