A circuit of a multi-phase active power filter based on multi-stage inverter architecture was introduced. The paper is focused on building the MATLAB / Simulink model of an AC power supply system including a single-phase active power filter with a two-stage inverter. Each stage of the filter uses the pulsewidth modulation (PWM) method. The results confirmed high efficiency of such a compensatin...

Full adder circuit is a basic building block for designing any arithmetic circuits.

This paper considers the joint repair and restoration of the electrical power system after significant disruptions caused by natural disasters. This problem is computationally challenging because, when the goal is to minimize the size of the blackout, it combines a routing and a power restoration component, both of which are difficult on their own. The joint repair/restoration problem has been ...

Level shifter is an interfacing circuit which can interface low core voltage to high input-output voltage. It allows communication between different modules without adding up any extra supply pin. The main objective of the work is to minimize power dissipation in shifter circuit, which is due to different supply voltages in the circuit.
