Level shifter is an interfacing device playing a wide application in System On Chip (SOC) design. Modern SOC utilize Multi Supply Voltage Design (MSVD) because of their low static and dynamic power consumption. When a high voltage supplied cell of SOC is driven by a low voltage supplied cell then their occur error due to inability of low signal to drive a high voltage cell. For interfacing thes...
in the present study, we investigate dc conduction mechanism of electron beam evaporated bromoaluminium phthalocyanine (bralpc) thin films using aluminum and gold electrodes. the current-voltage characteristics of sandwich type device are evaluated for the temperature range 298-413k under dark conditions. it is observed that the current passing through the device is increased by increasing te...
In PWM inverter-fed drives, a variation of Common mode voltage (CMV) causes unbalanced voltage operation in induction motor. Multilevel inverters reduce this problem, but the complexity of the power circuit increases with an increase in the number of inverter voltage levels. In this paper, a five-level inverter is compared with two, three and four levels and this five level structure is propose...
Common mode voltage (CMV) causes various issues, including a negative impact on the performance of hybrid electric vehicle’s power system (HEV). Many papers have published methods that mitigate CMV, almost all which attempt to avoid zero vectors, but this increases total harmonic distortion (THD). This work describes simple and efficient method for reducing CMV in two-level three-phase source i...
Even with the fluctuations in the network voltage, the AC voltage level at the customer terminals must maintain stable. The stabilization process offers a compensation holding the output voltage to protect the main equipments. This paper presents the merits of Discrete Stabilization as compared to phase and two-level voltage regulations. This paper proposes using of more complex block to the mu...
The inherent nature of normal boost converter has more voltage stress across the power electronics switch and ripple. The presented formation of the front end rectifier stage for a photovoltaic (PV) organization is mainly used to give the supply. Further increasing of the solar efficiency is achieved by connecting the zero voltage soft switching boost converter. The zero voltage boost converter...
This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new seven-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor se...
The voltage instability phenomena occur in both transmission systems and distribution systems. The weakening of voltage stability level will limit the growth of load served by distribution companies. Voltage instability in power distribution systems could lead to voltage collapse and thus power blackouts. The integration of distributed generation (DG) in the distribution system has increased to...
