Real time implementation of hybrid sine wave reference generator based on PLL and DLT

A sine signal synchronous to the power system voltage signal is required in most power electronics based industrial applications. In this study, a phase locked loop (PLL) and direct look-up table (DLT) based hybrid sine oscillator is developed, and sinusoidal signals of the desired frequency that is synchronous to the reference input signal is generated in real time applications carried out with the developed oscillator.
