“…The design starts by proposing a sliding-surface as a function of state-variables followed by the derivation of the equivalent control, and finally choosing the coefficients of the sliding-surfaces using stability condition [32,33]. Two different sliding-surfaces are proposed here; the first includes the inductor current feedback while the later employs capacitor current feedback.…”

Since the parasitic voltage ringing and switching power losses limit the operation of active devices at elevated frequencies; therefore, a higher‐order inductor‐capacitor (LC) filter is commonly used, which offers extended attenuation above the cutoff frequency and thus, improves the total harmonic distortion (THD) of the amplifier. This paper applies the concept of integral sliding‐mode control to a fourth‐order class‐D amplifier. Two fixed‐frequency double integral sliding‐mode (FFDISM) controllers are proposed, where one uses the inductor current while the other involves the capacitor current feedback. Their equivalent control equations are derived, but from the realization viewpoint, the controller using the capacitor current feedback is advantageous and, therefore, is selected for final implementation. The performance of the proposed FFDISM controller for fourth‐order GaN class‐D amplifier is confirmed using simulation and experimental results.

“…Interleaving and phase-shedding techniques are pillars that help to improve efficiency and ripple cancellation effect. Several works have been recently focused on the hysteretic mode controlled SMPS (Switched-Mode Power Supply) converters [1][2][3][4][5][6]. This type of control grows in popularity for fast transient response.…”

“…The switching action is compared with a clock reference F REF and the result V pll is fed back into the main loop. The traditional approach described in [2], [5] uses the frequency loop adjusting the delay of the main comparator. The comparator hysteresis band is adjusted in another approach mentioned in [3].…”

El presente trabajo muestra un análisis orientado a la propuesta de diseño e implementación de un doble controlador en modo deslizante para un convertidor Buck CD-CA. Se plantean las superficies de deslizamiento candidatas de acuerdo con las exigencias de la aplicación y, mediante una lógica de activación de las llaves semiconductoras (MOSFET), se obtiene un control independiente en la amplitud de la tensión para el semiciclo positivo y negativo de la onda de salida en CA, con el objetivo de lograr a voluntad un nivel de CD introducido en la señal de alterna. Se ingresan perturbaciones de tensión en la entrada del convertidor y se producen variaciones en la carga con el objetivo de probar la robustez del sistema de control propuesto. El control se implementa en un microcontrolador AVR Atmega164PA y se prueba de manera práctica. Finalmente, se expone una comparación de los resultados obtenidos de manera experimental con las simulaciones realizadas en SCILAB5.
