In this paper, a multi-level wordline driver scheme is presented to improve 6T-SRAM read and write stability. The proposed wordline driver generates a shaped pulse during the read mode and a boosted wordline during the write mode. During read, the shaped pulse is tuned at nominal voltage for a short period of time, whereas for the remaining access time, the wordline voltage is reduced to save t...

This paper addresses to enhance the stability of8T SRAM bitcell by lowering its leakage power. Scaling down of process parameters such as supply voltage affects the Read ability and Write stability of the cell. As number of transistors on chip increases power dissipation also increases and as a result of this stability of the cell gets affected. This paper aims at reducing the leakage power and...

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.

This paper presents a new centralized adaptive method under frequency load shedding. Sometimes, after initial frequency drop following severe disturbances, although the system frequency returns to its permissible value, however, the system might become unstable due to voltage problems. In this regard, the paper proposes a new centralized adaptive load shedding method to enhance the voltage stab...

Although LCL filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. Recently, the single-loop control strategy has beensuggested for L or LC filter based grid-connected inverters. However, the use of single-loopcontrol directly in LCL filter-...

This paper proposes a single-loop repetitive voltage control strategy which incorporates the active damping control feature for single-phase uninterruptible power supply (UPS) applications. The proposed method reduces the effect of the LC resonant peak, which limits the control bandwidth and deteriorates the stability of the entire control loop by effectively increasing the damping component. D...
