System and method of controlling an electronic inverter as nonlinear current source.

摘要

System and method for controlling a three-phase inverter source nonlinear, the inverter connected to load or phase grid being. The system comprises: # - means for measuring the Ucc voltage in the dc inverter; # - means for measuring the components (U {sub, a}, U {sub, b} U {sub, c }) of the load voltage; # - means for measuring the components (i {sub, a}, i {sub, b}, i {sub, c}) of the load current; # - means control charged: # - obtain the space phasor vector U {sub, g} (U {sub, {the}} U {sub, {be}}) of the measured voltage; # - obtain the space phasor vector i { sub, g} (i {sub, {the}} i {sub, {be}}) of the current measured; # - obtain the increased current {dl} vector i {sub, g} = vector i {sub , g} * {sub -vector i, g}, i being vector {sub, g} * (i {sup, *} {sub, {the}} i {sup, *} {sub, {}} be ) spatial reference current; # - calculate the space vector voltage vector U {sub, CONV} (U {sub, c {the}} U {sub, c {be}}) to apply to the current vector i {sub, g} i {evolve into sub vector, g} *; # - spatial modulation applied by phasors switching times of the transistors of the inve rsor.
