Two-dimensional electronics based on single-layer (SL) MoS2 offers significant advantages for realizing large-scale flexible systems owing to the ultrathin nature, good transport properties and stable crystalline structure of MoS2. However, the reported devices and circuits based on this material have low yield because of various variation sources inherent to the growth and fabrication technology...
Accurate modelling of photovoltaic (PV) modules is necessary to understand PV cell operation and to develop maximum power point tracking (MPPT) algorithm for efficient operation of the PV system. A variety of models are proposed in the literature that use a current source, diodes and resistors to represent a PV module. The parameter values involved in the model need to be accurately estimated to improve...
A scheme is presented to integrate a primary-side-sensing technique into a model-predictive-controller for a Flyback converter. The control circuit consists of a signal processor, an observer, and a model-predictive controller. Besides inheriting the advantages of model-predictive-control, e.g. optimal tradeoff between overshoot, fast stabilization and constraints handling, the proposed controller...
With the development of semiconductor technology, semiconductor switching devices have the advantages of fast switching speed, high stability, so they are popular in pulsed power research field, but the use of semiconductor switch causes the main circuit be complex and the cost increase, and the switching speed is limited by the drift velocity of the charge carriers for the particular device. So it...
An experimental scale-down model of UHVDC converter transformer is designed and manufactured to study the wave process in the winding under impulse voltage. Nine outgoing lines are set up on the different winding coil of the scale-down model. The voltage waveforms of different outgoing lines are obtained by lightning impulse test. The simulation model of scale-down transformer is established to calculate...
Through directly driving by a novel moving-magnet transverse-flux linear oscillatory motor (LOM), an integrated linear oscillatory compressor is presented in this paper. The compressor has the characteristics of simple manufacture process, good dynamic performance, small size and high efficiency. The basic structure of the integrated linear oscillatory compressor proposed is presented in Fig.1. The...
We present an antenna modeling method based on partial element equivalent circuit (PEEC) theory. The antenna is modeled as an equivalent circuit of lumped circuit elements, which enables circuit co-simulation between the antenna and circuits in both time and frequency domains. Antenna radiation is captured as an equivalent radiation resistor. For verification, a 2.4-GHz transmitter with bondwire antenna...
Role of dual AV nodal pathway physiology in the atrioventricular nodal (AVN) conduction during atrial arrhythmias remains unclear. By using His electrogram alternans (HEA), we have developed a functional model of the atrioventricular conduction that incorporates the dual AV nodal pathway physiology. Experiments performed on 5 rabbit atrial-AVN preparations were used to develop and test the presented...
