Standard lowand medium-power induction motor drives are based on the pulsewidth modulation (PWM) voltagesource inverter fed from a diode rectifier. The dual topology, based on the current-source inverter/rectifier structure is used in mediumand high-power applications. This paper analyzes the existing motor drives based on current-source topologies and proposes a control strategy that addresses...

This paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (SAPFs). This method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. Next, the amplitude of the reference mains currentis computed with ...

The present study aims at investigating the feasibility of using solar energy as a power source to run electro-kinetic remediation in order to clean-up lead from three types of Iraqi soil. In order to do so, it carries out six tests with enhancement conditions, involving pH control and injection wells. Conducted in the city of Baghdad, Iraq, the experiment, is divided into two groups so that th...
