This paper presents the control design for a high-gain transformerless DC-DC converter. Linear modeling is derived by means of small-signal analysis. Both single-loop and double-loop PI control schemes are studied and, the corresponding stability and exponential decay rates are computed by exploiting the continuity in the polynomial roots, which is reviewed in the verge of new stability analysis for power electronic converters. Transient response specifications are explored as a critical test of this method. Numerical results and simulations are tackled to support our proposal.
