To obtain the clean energy, the hybrid solar–wind power generation is used. Consumers prefer quality of power from suppliers. The quality of power can be measured by using parameters such as volt...

This paper presents a design methodology dedicated to multiphase Permanent Magnet Synchronous Machines (PMSM) supplied by Pulse Width Modulation Voltage Source Inverters (PWM VSI). Firstly opportunities for increasing torque density using the harmonics are considered. The specific constraints due to the PWM supply of multiphase machines are also taken into account during the design phase. All t...

The huge influence of the sampling rate on performance digital PID control a voltage source inverter (VSI) is revealed. It shown that an appropriately chosen continuous-time model controller with PWM power converter behaves like actual discrete-time system, which allows for simple analysis and design. variable structure nature both RC rectifier abruptly changing resistive load two modes operati...

Passivity-based control (PBC) seems to be predicted for the algorithms in voltage source inverters (VSI) backup systems. This paper presents limitations of improved (IPBC) version PBC (directly measuring output voltage) maximum and current gains. In a microprocessor-controlled inverter, these depend on PWM modulator dynamic properties, switching frequency, modulation index value (avoiding satur...

This paper presents the mathematical model and control of a voltage source inverter (VSI) connected to an alternating current (AC) microgrid. The VSI considered in this is six switches three-phase Pulse Width Modulated (PWM) inverter, whose output active reactive power controlled dq reference frame. strategy presented here state feedback with disturbance cancellation. signal either provided by ...

This paper presents the mathematical model and control of voltage source inverter (VSI) connected to an alternating current (AC) microgrid. The VSI used in this work was a six-switch three-phase PWM inverter, whose output voltages were controlled synchronous (dq) reference frame via sliding mode strategy. strategy required only voltages; other states system estimated by using high-gain observer...

Most of the pollution issues created in power systems are due to the non-linear characteristics and fast switching of power electronic equipment. Power quality issues are becoming stronger because sensitive equipment has been more sensitive for market competition reasons, equipment will continue polluting the system more and more due to cost increase caused by the built-in compensation and some...

The increasing use of power electronic based loads (adjustable speed drives, switch modern power supplies, etc) to improve system efficiency and controllability is increasing concern for harmonic distortion levels in end use facilities and on overall power system. The Active Power Filter uses power electronic switching to generate harmonic currents that cancel harmonic content from non – linear...

Selection of proper reference compensation current extraction scheme plays the most crucial role in the performance of an active power filter (APF). This paper mainly describes three different control schemes used in APFs namely, Conventional instantaneous active and reactive power (p–q), Modified p–q, and Instantaneous active and reactive current component (id–iq) schemes. Our objective here i...
