Synchronous PI controller is usually used to track current in three-phase PWM rectifier with zero steady-state error which is difficult to achieve in the single-phase system. A novel proportional-resonant (PR) control scheme for single-phase PWM rectifier is proposed in the paper. Compared with traditional PI control and current hystereis control (CHC) methods, the PR control structure is simple and...
This paper presents a band-stop tunable filter (BSF) within frequency ranges of 7-13.5GHz and it shows good stop rejection and sharp roll off frequency. It used a novel design to turn the resonant frequency by microelectromechanical systems (MEMS) switch and coplanar-waveguide (CPW) structures. The DC voltage is utilized to load RF-MEMS switch as source of the tunable cell's power. This paper also...
