The operation of electromedical equipment in health care centers is very dependent on the quality of electrical power. Disturbances such as voltage sags, also known as dip voltage, can disrupt the performance of sensitive electronic devices and potentially threaten the stability of a power distribution system. This study suggests the use of a Dynamic Voltage Restorer (DVR) equipped with feedforward control to reduce voltage sags. With long flashes and significant voltage drops, simulations using MATLAB/Simulink show that the feedforward control on the DVR is able to compensate for voltage sags correctly and on time while still maintaining a stable load voltage.
