Circuit converter control system

The invention provides a circuit converter control system which is electrically connected to a circuit converter including an input stage circuit, a load switch and an output stage circuit. In the circuit converter control system, a filter is sued for sampling a historical feedback average voltage according to feedback output voltages at different times for digital signals output by an output end at different times; a control module is provided with a voltage threshold, and is used for receiving immediate feedback output voltages for the digital signals output by the output end and detecting the load state of the circuit converter based on the historical feedback average voltage; and the control module controls the load switch at a control duty cycle, increases the control duty cycle for controlling the load switch when the load state is changed from a light load state to a heavy load state and the voltage difference value reaches the voltage threshold, otherwise reduces the control duty cycle. Therefore, the
