The simulation and implementation of a step-down frequency-modulated zero-current switching quasi-resonant converter (FM-ZCS-QRC) fed DC drive are presented. A parallel resonant QRC is used for the speed control of a DC motor. The FM-ZCS-QRC-fed DC drive is modelled and simulated. A microprocessor-based prototype system is also implemented for controlling the drive speed and the results predicted by simulation are verified experimentally. It is found that the FM-ZCS-QRC-fed DC drive has several advantages over those fed from phase-controlled converters, DC choppers and PWM converters.

This study delved into leveraging deep learning techniques to classify different types of cervical cancer images, recognizing the disease’s prevalence and criticality. We employed a dataset comprising cervical images and investigated the utilization of the VGG16 model as a foundational architecture. To enhance performance, we incorporated various improvements, such as L2 regularization and data augmentation. The outcomes underscored the efficacy of these enhancements, with the refined model achieving a remarkable accuracy of 94%, surpassing the VGG16 model’s baseline accuracy of 89%. These findings demonstrate the potential of deep learning to improve the classification of cervical cancer.
