Closed-loop control inverters are gaining ever-wider application in various power scenarios such as medical, industrial and military. The requirements for the steady-state and dynamic performances of their output voltage waveforms are becoming increasingly demanding under various load conditions.
represents a new digital control loop for PV inverter, in which phase shift is controlled by the grid voltage and the inverter voltage. A digital pulse width modulation is generated to control the switching of the PV inverter and the regulation of reactive power will be done by using closed loop strategy.
In this paper, the proposed system leads to the improvement of power output by controlling of the voltage parameter. These systems developed using a closed loop voltage control strategy and produces a voltage having constant amplitude and frequency, which helps to improve the overall output power quality of inverter.
The closed-loop inverter simulation gives desired three-phase output voltage and current whereas L – C filter keeps harmonic contents of the output voltage and current under 5% (IEEE 519). The proposed system is simulated for different loading conditions that maintain a constant output voltage with better controllability and dynamic stability.
