Este artículo presenta un nuevo método de control para un convertidor Boost con corrección del factor de potencia en configuración de medio puente (CCFP-MPE). En el control propuesto, se adiciona un lazo de pre-compensación que elimina el error en estado estacionario de fase en el control de corriente. Por lo tanto, se logra una mejora en el factor de potencia incluso en condiciones de baja carga y variaciones en el voltaje de la fuente. En el documento se detalla la metodología de diseño del circuito, que incluye, la obtención de la función de transferencia a través del modelo de circuito promedio, el diseño de los controladores que conforman el circuito, el método de eliminación del desbalance de voltaje y el diseño del pre-compensador junto con su análisis, evaluando el efecto en la estabilidad del sistema. Finalmente, se realiza un montaje experimental en el que se definen dos casos de estudio y se presentan los resultados correspondientes, con el fin de validar el controlador propuesto

Abstract:In this paper, we propose adaptive nonlinear controllers for the Single-Ended Primary Inductance Converter (SEPIC). We also consider four distinct situations: AC-DC, DC-DC, Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). A comparative analysis between classic linear and nonlinear approaches to regulate the control loop is made. Three adaptive nonlinear control laws are designed: Feedback Linearization Control (FLC), Passivity-Based Control (PBC) and Interconnection and Damping Assignment Passivity-Based Control (IDAPBC). In order to compare the performance of these control techniques, numerical simulations were made in Software and Hardware in the Loop (HIL) for nominal conditions and operation disturbances. We recommend adaptive controllers for the two different situations: Adaptive Passivity-Based Feedback Linearization Control (APBFLC) for the PFC (Power Factor Correction) AC-DC system and IDAPBC-BB (IDAPBC Based on Boost converter) for the regulator DC-DC system.

“…The input current distortion due to the DCM operation includes high-order harmonics, which are higher than the bandwidth of a typical current controller such as a proportional-integral (PI) controller or a proportional-resonant (PR) controller. To reduce the input current distortion, the current controller should be designed considering the plant model in DCM as well as in CCM [27,30,31]. In [27], the feed-forward is utilized in the SEPIC PFC converter for compensating the input current distortion.…”

Design and Analysis of a Repetitive Current Controller for a Single-Phase Bridgeless SEPIC PFC Converter

This paper studies a repetitive controller design scheme for a bridgeless single-ended primary inductor converter (SEPIC) power factor correction (PFC) converter to mitigate input current distortions. A small signal modeling of the converter is performed by a fifth-order model. Since the fifth-order model is complex to be applied in designing a current controller, the model is approximated to a third-order model. Using the third-order model, the repetitive controller is designed to reduce the input current distortion. Then, the stability of the repetitive controller is verified with an error transfer function. The proposed controller performance is validated by simulation, and the experiment results show that the input current total harmonic distortion (THD) is improved by applying the proposed controller for an 800 W bridgeless SEPIC PFC converter prototype.
