A LCLC series-parallel high-frequency ac/ac resonant inverter configure for ion assistant vacuum-sputtering manufacture film is proposed. The characteristic of the sputtering chamber and a simplified steady-state analysis of the inverter, using complex circuit analysis, are presented. The control implementation circuit block diagram is introduced to the resonant inverter, which can implement the output...
In this paper an all digital phase-locked loop (ADPLL) that is based on double edge triggered D-flip-flops (DETDFF) was proposed. By using DETDFF, the functions of bi-directional zero crossing sample and phase detection, which are key issues in the designing process of ADPLL with several new important characteristics, were implemented. In addition, the run speed of each part in the loop was enhanced...
