Abstract
A strategy is proposed to control the output voltage of a three-phase PWM-controlled rectifier, based on the synchronverter technology that operates PWM converters to mimic synchronous machines. Such a PWM-controlled rectifier is able to track the grid frequency and phase so that an extra synchronisation unit, e.g. a phase-locked loop (PLL), is not needed any more, which considerably reduces the computational burden of the controller. The strategy is verified with simulations in Matlab/Simulink.
