Current Mode Control

Current-mode control of buck converter has been described in the previous page. The method to be used for boost converter is more or less the same. Here also slop compensation is needed in order to ensure stability. Compensation to be added to signal reflecting inductor current is a fraction of the ramp signal, where the fraction is computed according to equation (49). The sixth applet that follows simulates the boost converter circuit with current-mode control. The program may take a while to display periodic responses, whereas transient responses are displayed with no significant delay.
