Abstract

Behaviors of loop-gain functions and other control transfer functions are critically important in the design of current-mode DC/DC converters. In this paper, procedures were proposed to use SIMPLIS to simulate the two loop gain functions T₁ and T₂, the equivalent control plant transfer function when the inner loop is closed F_in, current loop gain T_i and voltage loop gain T_v. These models are practical to obtain, simple to use, accurate beyond switching frequency and are easily amendable to incorporate new converter configurations and new control schemes
