About

Miquel Ricart Oltra is a pioneering researcher in power electronics, with a focus on ultra-high-ratio DC-DC converters for emerging robotic and portable applications. His most cited work introduces a groundbreaking Dual-Transformer Hybrid Converter capable of achieving an extreme 2000X conversion ratio—transforming a standard 1-cell battery input (as low as 2.5V) into a 5kV output while delivering 15W of power. This topology, designed specifically for soft mobile robots, overcomes fundamental limitations of conventional converters by combining two transformers with a hybrid switching architecture, enabling unprecedented voltage step-up without sacrificing efficiency or size. With 12 citations, this 2020 paper has become a reference point for researchers tackling high-voltage generation from low-voltage sources. Ricart Oltra’s contributions are particularly notable for addressing the power supply challenges of next-generation soft robotics, where lightweight, compact, and extreme-ratio converters are essential. His work bridges the gap between circuit theory and practical robotic systems, offering a scalable solution for dielectric elastomer actuators and other high-voltage loads. For students and engineers, his research exemplifies how creative topology design can unlock new capabilities in autonomous systems.
