Abstract: This paper presents a voltage mode universal biquadratic filter with one input and five output terminals, realizing all the standard filter functions that are high pass, band pass, low pass, notch and all pass, without changing the circuit topology. The proposed circuit employs three plus-type differential difference current conveyors (DDCCs), three grounded resistors and two grounded capacitors. The proposed filter enjoys the features of high input impedance and low active and passive sensitivities. PSPICE simulation results are given to confirm the validity of the proposed circuit.

Abstract: This paper presents a comparative study of single phase multilevel AC/DC converters. The simulation results are analyzed for different topologies with variations in load current and input power supply keeping the reference output voltage constant. In all the topologies only pulse width modulation (PWM) control scheme is used with hysteresis current controller. Simulations are carried out in MATLAB SIMULINK for fundamental frequency of 50 Hz for resistive loads only. Performance analysis shows that structure of these topologies have wide use in industrial applications as they have nearly unity power factor.
