A new model of Interphase Power Controller (IPC) for controlling active power is introduced in this paper. In this model, which is called VSC-based IPC, the voltage source converter (VSC) does the function of the phase shifting transformer (PST) in IPC. This new structure not only has the features of IPC, but also controls the output power effectively when the input power is changed by alternat...

In this paper a new high gain bandwidth (GBW) and low power folded cascade OPAMP is presented. It has been implemented and layouted by CADENCE software in 0.18μm. Its DC gain is 82db and its bandwidth is 200MHz. Power consumption is one of the main design challenges in very-lowvoltage high-speed analog integrated circuits. In this paper, different techniques to reduce the power consumption in l...

As the deployment of distributed generation continues, an increasing number of DC/AC power inverters will be interfaced into the electric grid. Groupings of these power inverters, along with distributed storage and load, are referred to as microgrids. Microgrids offer the potential for unprecedented reliability and flexibility, but also pose new control challenges. Inverters in microgrids must ...

This paper explains about the voltage output for DC to DC boost converter between open loop, PID controller and fuzzy logic controller through Matlab Simulink. Simulink input voltage was set at 12V and the voltage reference was set at 24V. The analysis on the deviation of voltage resulted that the difference between reference voltage setting and the output voltage is always lower. Comparison be...

Efficiency of Orthogonal Frequency-Division Multiplexing (OFDM) system is improved by reducing the power consumed by its transmitter and also by improving the spectral efficiency. Power usage is reduced by reducing the PAPR of OFDM system and spectral efficiency is improved by Adaptive modulation and coding schemes (AMC). In OFDM system, transmission signals can have high peak values in the tim...
