Abstract In the paper, the product-type PLL system, which is so suitable for synchronizing a single phase grid voltage is designed. The PLL system is modelled with the small signal analysis. Both the cut-off frequency of low pass filter and the optimal gain are derived by considering the transient response for synchronization as well as a distortion of synchronization signal. Through the simulation studies and experimental results, the transient response and ripple component of synchronization signal are investigated with a variation of both the cut-off frequency and gain in order to verify the performance of design.
