Design of Current Controllers for Three Phase Voltage PWM Converters for Different Modulation MethodC). In order to achieve a good performance, the voltage source inverter (VSI) should be commanded by a current controller to track as accurate as possible a current reference. Pulse with modulation (PWM) and space vector modulation (SVM) are two techniques used in VSIs to generate the time average o

Limits of Harmonic Power Recovery by Power Quality Conditioners in Three-Phase Three-Wire Systems Unances. Such protection feature brings mostly intangible benefits that are difficult to quantify in monetary terms. This is the reason why some providers of power quality solutions focus more on promote energy savings benefits rather than emphasize the protection feature at the time of advertising th
