N2 - Conventional orthogonal signal generators (OSGs) employed in single-phase systems exhibit significant delay in tracking the original signal. To tackle this problem, an OSG with fast synchronizing speed is proposed by applying the principle of power definition of sinusoids. The proposed OSG can accurately track the single-phase input signal in less than half cycle, which is one cycle faster than the widely used OSGs. Depending on the application, the proposed OSG can be modified to meet application-based requirements. The proposed OSG in a single phase frequency locked-loop (FLL) implementation is firstly introduced in this paper. In addition, the ability of a low-pass filter to act not just as a filter, but to eliminate steady-state error is revealed. Through experimental comparison with Park and SOGI OSG-based FLLs, it is shown that the proposed OSG-based FLL provides faster estimation of frequency and phase angle of a single-phase voltage.
