摘要：

The design of step dynamic voltage regulator is considered for the purpose of restoring load voltage without incurring excessive phase angle shift. As a type of custom power device devoid of any significant energy-storage capability, the process of voltage restoration by the regulator has to depend on the power in-feed from an external supply system. As a consequence, the analysis shows that there are inherent limits imposed on the device for achieving successful voltage restoration. Pertinent expressions are derived which relate the limits to the parametric values describing the supply system and loads. When the expressions are used in conjunction with a proposed computational procedure, a method to determine suitable regulator design for the purpose of power quality enhancement is obtained.
