Research on the Control Strategy of Boost-type DC-DC Converter with Capability of Strong Suppressing Disturbances
As a fixed value control system,the interference of the boost-type DC-DC converter system is particularly important.In order to improve the anti-interference ability of the Boost system,this article analyzes the small signal model of the Boost-type DC-DC converter in detail.Meanwhile,with the help of the system characteristics when the Voltage—Mode control strategy is employed with and without input voltage feed-forward,a new control method named input voltage feed-forward—Voltage-mode Control is introduced,which can fast suppress the input voltage and output current disturbances.Especially the input voltage disturbance can be removed completely in approximation.And then on the base of analyzing the Two Pole—Two Zero controller,it also offers a method of fast deciding the control parameters for the new control strategy.According to the simulation,the superiority of the new control strategy’s Capability of Suppressing Disturbances and the rationality of the method of the parameter selection are proved.The thinking of this control method also can apply to other DC-DC converters.
