The power circuit consists of three-phase AC supply with a grid line voltage of 380 V, three inductors, three-phase rectifier, DC-DC Cuk converter, FSI, and IM.
Figure 4 shows phase waveforms of deformed network voltage through a three-phase rectifier [u.sub.S1], voltage generated by filter [u.sub.C1] and compensated voltage [u.sub.L1] for the comparative method and resistive-inductive load.
Three-phase rectifier with star connected diodes belongs to the most popular insulation monitoring systems (Fig.
Since the shunt APF topology is identical to that of an active three-phase rectifier [14], the circuit boosts the DC-link voltage using an external voltage control loop that generates a loss power control signal, [p.sub.loss], which is added to [??] to supply energy for the DC-link capacitor and compensate the power losses of the APF circuit.
It features voltage source inverter (VSI) topology with a three-phase rectifier, DC link and multi-level output converter using Neutral Point Clamped (NPC) technology with 3/5 voltage level for output voltages from 2.3 kV to 4.16 kV or 5/9 voltage level for output voltages from 6.0 kV to 6.9 kV.
Unique impact of three-phase rectifier on dynamic studies compared with conventional models is evaluated by using its validated model in transient stability analysis of IEEE 9-bus test system performed by PSCAD/EMTDC.
