The model of static VAr generator (SVG) is carried out by state space averaging modeling and instantaneous reactive power theory. Based this model, the bivariate PI control strategy is applied in SVG. The DC-voltage reference is unascertainable in the control strategy, because of the equivalent resistance of the model is a nonlinear variable. Based on the model, the accurate mathematical model of...
This paper introduces a novel current-mode biquadratic circuit using only plus type differential voltage current-controlled current conveyors (DVCCCs) and grounded capacitors. The biquadratic circuit is constructed with two plus type dual current output DVCCCs (DO-DVCCCs) and two grounded capacitors. The circuit can realize biquadratic circuit transfer functions by choosing the appropriate input and...
The electric behavior of compact fluorescent lamps is analysed. In static conditions the lamp has a nonlinear voltage-current characteristic. In dynamic conditions the lamp has a dynamic conductance related to the static conductance by a differential equation. The lamp is simulated in two different circuits: one with a series reactor and another with a series reactor and a small capacitor in parallel...
