This paper presents an effective approach to simultaneous solution of capacitor setting and feeder reconfiguration for power-energy loss reduction and voltage profile enhancement in radial distribution systems. An optimization method using a Genetic Algorithm is proposed to determine the optimal selection size, location, type and number of fixed or switched capacitors as well as the open/closed...

Synaptic dynamics, such as long- and short-term plasticity, play an important role in the complexity and biological realism achievable when running neural networks on a neuromorphic IC. For example, they endow the IC with an ability to adapt and learn from its environment. In order to achieve the millisecond to second time constants required for these synaptic dynamics, analog subthreshold circ...

Switched reluctance motor (SRM) drive has a remarkable characteristic, high efficiency, and good controllability, which makes it attractive for high-speed applications. In this paper, the basic control strategy for a switched reluctance motor drive circuit is explained and then three different resonant discharge topologies for SRM drive circuit are proposed. Due to resonantly discharging of exc...

The first major concern in clocking an SCF is the clock's duty cycle. Deviation from the range specified by most manufacturers (40% to 60%) produces inadequate settling of the switched-capacitor element, which can cause signal distortion, inaccurate filter response, and signal attenuation. Most sources inherently produce the desired 50% duty cycle; if not, that performance can be ensured by des...
