Improving Power Distribution in Wearable Technology on Simultaneous Bidirectional Converter

Abstract

This research addresses the critical challenge of improving power distribution in wearable technology by introducing a novel simultaneous bidirectional converter designed for enhanced efficiency and better energy factors. The proposed converter architecture significantly reduces ac/dc power source wastage, commonly associated with harmonic difficulties and voltage level drops in wearable devices. The design features two key components: the first transformer operates as a dc/dc phase, adjusting the switching frequency to control the reference voltage, while the second serves as an ac/dc converter, focusing on transformer efficiency and distortion reduction. A key innovation in this architecture is the bidirectional inverting amplifier, which synchronizes voltage output with any output waveform by adjusting the multimeter settings and altering the interval, while keeping the switching on-time constant. This approach notably enhances frequency deviation, reducing output current drop by nearly 70%, and simultaneously lowers overall harmonic distortion, leading to cost savings.
