The paper introduces a full-open experimental platform for doubly-fed induction generator (DFIG), which based on wind energy conversation system. The paper starts from the working principles of doubly-fed induction generator (DFIG), then the controlling strategies of gird-connection and variable- speed-constant-frequency (VSCF) and maximum-power-point- tracking. The effects of the controlling strategies...
A diode-clamped three-level dual-boost reversible PWM rectifier is proposed in this paper. As this topology is deduced from the dual-boost PWM rectifier, it inherits the merits of no hidden danger of shoot-through and no body diodes' reverse recovery problems, which are the two main problems of the conventional half-bridge and full-bridge rectifiers. Thus, the proposed circuit has the advantages of...
The functions of neural system, such as learning, recognition and memory, are emerging from the dynamic mechanisms of neurons and synapses. A dynamic neural network is designed to discuss how the dynamic mechanisms in the neurons and synapses work in recognizing interspike intervals (ISIs). The dynamic synaptic transmission mechanisms and the properties of integrate-and-fire neurons are the key mechanisms,...
