Abstract

This paper presents an approach for the effective control of the output voltage of Boost converters operating in continuous conduction mode, addressing the challenges associated with the presence of a non-minimum phase zero (RHPZ) in their transfer function. The use of a controller designed in the frequency domain using the K-factor method is proposed to compensate for this RHPZ and enhance system stability. The theoretical and practical tests conducted demonstrate that the proposed controller is capable of efficiently mitigating the effects of the RHPZ, resulting in significant improvements in system performance regarding stability and output voltage regulation. This work contributes to the advancement of the field of power converter control, providing an effective solution to the challenges faced in the continuous conduction mode of the Boost converters.
