This paper presents a three-phase four-wire Shunt Active Filter that compensates power quality problems and can also interface renewable energy sources with the electric grid. The inverter stage of the active filter is based in a two-level four-leg inverter and its control is based in the Theory of Instantaneous Reactive Power (p-q Theory). The filter is capable of compensating power factor, un...

The steady state analytical performance of a line commutated inverter fed three phase synchronous motor under variable speed condition is presented. The firing pulses for six silicon-controlled-rectifiers of the three phase inverter are generated by the control circuit in proper sequence with the help of synchronizing signal derived from the induced electromotive force of the synchronous machin...

This paper proposes two methods to improve the performance in real-time simulation. The increased inverter-based generations are gradually shifting operation of power grid. Consequently, investigation for safe and further application is essential inverter-dominated As simulated number non-linear switch elements like inverter increases, numerical complexity simulation model rises exponentially. ...

Fault-tolerant control of a three-phase inverter can be achieved by performing hardware reconfiguration the six-switch and (6S3P) topology to four-switch (4S3P) after detection localisation faulty phase. Together with reconfiguration, SVPWM algorithm must appropriately modified handle new 4S3P topology. The presented study focuses on diagnosing faults in two steps: fault localisation. Fault is ...
