Where should I mainly focus on , to get high efficiency, breakdown torque, power factor in 3 phase squirrel cage induction motor for EV ?

Dear All,

I am working on hysteresis current controller with the inputs are the reference sinusoidal currents for the three phases and the actual three phase currents. the output of the controller is the gate signal for inverter. when I change the switch on and switch off values in relay block parameters in Simulink, there was no change in the controller performance and gate signals!!! and this against the logic expectations of the change in switching pattern of inverter and then the controller performance. Does anyone help me to know the reasons for this issue and how to solve.

I am grateful in advance.

I am researching the analysis of power systems in the Matlab simulink environment. I'm studying power systems with various numbers of busbars, such as 5,9,14.

I am looking for non-renewable energy alternatives for renewable energy indexes, namely ECO, ERIX, SPG, and SUN.Any suggestions are highly appreciated.

Emerging multi-stage amplifiers such as the four and five stages show intense demands regarding DC gain. It is evident that cascode amplifiers are losing their compatibility since they can not satisfy voltage swing requirements with recent technology. The reason behind this is the fact that recent integrated circuit technologies reduced supply voltage value considerably while threshold voltages remained constant relatively. So direct consequence is difficulties in designing vertical arrangments of MOSFETs. As a result, the tendency turns to Cascade more than Cascode. This path highlights the frequency compensation strategy since multi-stage amplifiers possess more nodes than conventional cascode amplifiers. This means that the major challenge for multi-stage amplifiers is compensation since almost any desirable DC gain value is obtainable easily. In this condition, numerous compensation methods are presented by researchers. The issue is that compensation networks become more and more complicated with lots of extra elements. For instance, I personally dealt with some multi-stage amplifiers while compensation networks were made by Miller capacitors and active gain stages. This shows that complexity is a real concern. So is there any alternative for cascode and cascade structures?

I want to have a normal distribution of PV or Slack bus voltages in order to calculate the mean and the variance... The results of the simulation always give a constant value for the slack and PV bus as the voltage have to be known and predefined.

I am trying to implement a closed-loop control strategy for a DC-DC (boost) converter. I designed the controller per well-known guidelines and successfully implemented it in MATLAB Simulink. The simulation results are absolutely fine. However, when the same controller is being implemented on a platform like dSPACE to trigger a real converter, the control signal i.e, the duty cycle upper saturation limit is reached.

Why does this happen for a controller which was well behaving in the simulation?

What are the potential reasons for this problem?

What should be done to rectify this problem?

Please help me out with some specific suggestions in this regard.
