Multi-port converter with three active full bridges, two series-resonant tanks and a Multi-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load and a renewable source such as fuel cell. The converter has capabilities of bidirectional power flow in the battery and the load port. Use of series-resonance aid...

Compliance is a strong requirement for human–robot interactions. Soft-robots provide an opportunity to cover the lack of compliance in conventional actuation mechanisms, however, control them very challenging given their intrinsic complex motions. Therefore, soft-robots require new approaches e.g., modeling, control, dynamics, and planning. One strategies that ensures impedance control. During ...

A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...

Abstract Pennate muscle is characterized by fibers that are oriented at a certain angle (pennation angle) relative to the muscle’s line of action and rotation during contraction. This fiber amplifies shortening velocity muscle, match loading conditions without any control system. unique variable gearing mechanism, which Architecture Gear Ratio (AGR), involves complex interaction among three key...
