This paper presents a copyright-based double integral sliding-mode (CBDISM) controller for a SiC class-D amplifier to compensate the $Q$ -factor and ensure a flatter frequency response. The copyright-based approach guarantees the fixation of switching frequency and improves the total harmonic distortion plus noise (THD + N) by reducing the effect of nonlinearities in the power ... https://macorners.shop/product-category/metal-ornament/
