Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Novel Control Scheme of Three-Phase Six-Level Hybrid Flying-Capacitor Inverters With Self-Balancing Capability

IEEE Access
In this paper, a novel control scheme is proposed for the recently developed six-level hybrid flying-capacitor inverter. In the conventional scheme, an auxiliary balancing circuit is required to regulate the voltages of split DC-link capacitors.

Model Predictive Control of an Asymmetric Flying Capacitor Converter

IEEE Transactions on Industrial Electronics, 2009
Multilevel converters and, in particular, flying capacitor (FC) converters are an attractive alternative for medium-voltage applications. FC converters do not need complex transformers to obtain the DC-link voltage and also present good robustness properties, when operating under internal fault conditions.
