Efficient Non-Isolated DC-DC Converter Using Variable Switching Frequency Control
Main Article Content
Abstract
A load adaptive high efficiency dc-dc converter with optimized switching control is proposed in this paper. The converter is controlled through the switching frequency auto-tuning over a full range of load changes. The load current tracking using a single current sensor is implemented with real-time computation of the desired switching frequency. It presents the latest algorithm to adopt the loading condition while keeping the output voltage constant. The algorithm is employed with a low-cost microcontroller having the capability to maintain dynamic performance through DPWM operation. In different operational conditions and with varying parameters, the converter continually retains the higher switching frequency. This proposed AFO (Adaptive frequency Optimization) controller performance is presented through simulation using MATLAB/SIMULINK and results are verified on a 100W DC-DC converter.
