Research on a Wide-Output Resonant Converter with Multi-Mode Switching
Energies, 2022 In this article, a resonant converter based on a series-parallel self-adjusting rectifier structure is proposed. By changing the driving signal of the switch, the converter has four working modes: full-bridge structure frequency modulation control, full ...

Antagonistic co-contraction can minimize muscular effort in systems with uncertainty [PDF]
PeerJ, 2022 Muscular co-contraction of antagonistic muscle pairs is often observed in human movement, but it is considered inefficient and it can currently not be predicted in simulations where muscular effort or metabolic energy are minimized. Here, we investigated
