The continued interest in the use of distributed generation in recent years is leading to the growth in number of distributed generators connected to distribution networks. Steady state voltage rise resulting from the connection of these generators can be a major obstacle to their connection at lower voltage levels. The present electric distribution network is designed to keep the customer volt...

The design and breadboard implementation of a constant-frequency, zero-voltage-switched, full-bridge pulsewidth modulation converter delivering a 12-V-at-1-kW output from a 350–450-Vdc input bus is described. The zero-voltage switching characteristic is maintained over a wide operating range by utilizing the transformer magnetizing inductance as an energy storage element. Output voltage regulat...

Regulation of mitochondrial outer membrane (MOM) permeability has dual importance: in normal metabolite and energy exchange between mitochondria and cytoplasm, and thus in control of respiration, and in apoptosis by release of apoptogenic factors into the cytosol. However, the mechanism of this regulation involving the voltage-dependent anion channel (VDAC), the major channel of MOM, remains co...

─An on chip low drop out voltage regulator that employs elegant compensation scheme is presented in this paper. The novelty in this design is that the device parasitic capacitances are exploited for compensation at different loads. The proposed LDO is designed to provide a constant voltage of 1.2V and is implemented in UMC 180 nano meter CMOS technology. The voltage regulator presented improves...

It ́s common practice in designing switchedcapacitor converters (SCC ́s) to keep charge-pump (CP) switches continuously commuting at light loads [1-2]. However, the resulting simplification in the control circuitry is frequently objected, as the switching dissipation prevails over the average power delivered to the load. Since the converter efficiency is degraded, such an approach does not comply...

A novel market design is proposed and developed that uses the energy-balance services for transmission-congestion relief. In this proposed market, all generators and customers have the ability to submit their offers to increase/decrease their generation/consumption, respectively. Each participant provides a ‘price–quantity’ offer to the independent system operator (ISO) which is independent of ...

Forward converters generally exhibit poor power factor when employing in the AC-DC conversion, due to the presence of zero input current near the zero crossing of line input voltage. In this paper, a single-switch forward converter with high power factor and low storage capacitor voltage stress is proposed. By adding a stack up voltage on top of the reflected input voltage on the forward conver...

This review addresses the localized regulation of voltage-gated ion channels by phosphorylation. Comprehensive data on channel regulation by associated protein kinases, phosphatases, and related regulatory proteins are mainly available for voltage-gated Ca2+ channels, which form the main focus of this review. Other voltage-gated ion channels and especially Kv7.1-3 (KCNQ1-3), the large- and smal...
