摘要
Abstract
Higher resolution and faster response are required for open-loop current control inverters than for closed-loop current control inverters. A high efficient digital phase locked loop (DPLL) was implemented for grid-connecting applications. The algorithm was implemented on the rotating d-q model with Bang-Bang control to regulate the phase angle of grid voltage through only 4 multiplications and a logic look-up table. The frequency was regulated in the digital controlled oscillator (DCO) by internal mode incremental algorithm. Stability and convergence analysis was guaranteed with Lyapunov method and further applications were discussed.
