Grid conected inverter for alternative sources of energy

Abstract

The general characteristic of power electronic couplers for alternative energy sources with electrical power grid was presented. The power electronic current source, working as a closed loop system, generating sine wave shaped current transfering the energy to the grid was discussed. The chosen results of simulation model of such system for sinusoidal reference signals were presented. The test results of the laboratory prototype were also presented.

Grid conected inverter for alternative sources of energy

“…The system consists of controllable modulated voltage source e M (t) as the voltage inverter with current output, supplied from the DC voltage source. The control signal s z (t) is generated by the corrector of the main track in closed current feedback loop system, defined according to the rules presented in the works [3,4]. On the output of modulated voltage source is passive demodulator (DM block), which acts like lowpass filter.…”
