This strategy enables the inverter to control both the magnitude and angle of current. Therefore, vector control using this strategy can lead to better output torque dynamics compared to the conventional slip frequency control with six-step voltage, which is widely used in traction drives. In this strategy, the d-axis output voltage of a current controller to control the flux is conserved and the q-axis output voltage to control the torque is controlled to place the voltage vector on the hexagon boundary in case of overmodulation. The limited q-axis voltage is used for anti-windup of q-axis current controller. This paper also presents a new field weakening scheme which incorporates the proposed overmodulation strategy. In this scheme, the flux level is selected by both required current limit and the available maximum voltage along hexagon sides. The validity of the proposed overall scheme is confirmed by computer simulation and experiments with a prototype setup.","PeriodicalId":287192,"journal":{"name":"APEC '99.

After switching, these circuits behave like a linear circuit. Therefore, linear circuit analysis methods can be used. In the simulation, capacitors and inductors are replaced by voltage and current sources respectively, whose values are determined by their current and voltages in the previous step. The method is based on solving a system of algebraically modified nodal equations at each integration step. The technique requires only DC analysis. The writing or solving of time-differential equations or Laplace transform inverses are not required. Thus, the simulation is fast and the simulation time is essentially the same as for a linear, time-invariant circuit of the same complexity. A simulation algorithm is given and an example is included.","PeriodicalId":287192,"journal":{"name":"APEC '99.

Especially, for high power variable speed applications, the diode clamped configuration multi-level inverter has been widely used. However, the diode clamped configuration inverter has the inherent problem that the potential of the link capacitor fluctuates. This paper describes a carrier-based SVM (space vector modulation) method to effectively suppress the DC link potential fluctuation for the diode clamped four-level inverter. The current to flow from/into each link capacitor is analyzed and the operation limit is obtained when a conventional carrier-based SVM method is used. To overcome the operation limit, a modified carrier-based SVM method is proposed. Various simulation results by means of Matlab/Simulink are presented to verify the proposed carrier-based SVM method.","PeriodicalId":287192,"journal":{"name":"APEC '99.

Also, this technique is suitable for not only minority but also majority carrier semiconductor devices. The auxiliary circuit of the proposed topologies is placed out the main power path, therefore, there are no voltage/current stresses on the main switch and diode.

While many other topologies have been proposed, only this inverter allows full independent control of the unipolar currents desired in each phase. This paper explores the use of inverters based on the three phase bridge topology and demonstrates their suitability for both the short pitched winding and fully pitched winding switched reluctance machine. Both machine and power electronic efficiencies are compared so that the benefits in terms of pure technical performance and cost can be assessed. Current sensing arrangements are also examined and results from a prototype drive demonstrate the effect that the number and position of sensors have on the ability to control the current to the desired value. The impact on the cost of the power electronics is assessed and a comparison is made with the induction motor drive in terms of peak VA, RMS and mean device current.","PeriodicalId":287192,"journal":{"name":"APEC '99.
