Voltage differential feedback control system based on repetitive control is proposed in this paper. The scheme, which can improve the dynamic characteristic and steady state performance by Capacitor voltage as outer loop while its differential as inner loop without current sensor, is achieved on a three-phase PV inverter with TMS320F2808. Two different control strategies, traditional and repetitive control , have been applied in three-phase PV inverter platform. The experiment results indicate repetitive control system has a faster dynamic response and a more accurate output regulation than those of traditional one.

A CMOS digitally programmable lossless grounded inductor is presented in this paper. It uses two digitally programmable second generation current conveyors (DPCCII) and three grounded passive elements including one capacitor only. The inductance value is tuned by programmable gain factor of current conveyor. As an application, a current mode multifunction filter has been realized using proposed programmable inductor. The simulation results have been demonstrated and discussed using a SPICE simulation.
