Inductively power transfer systems are becoming increasingly popular in modern applications like electric vehicles. An essential part of these systems is the control algorithm. This algorithm enables the power transfer according to the battery conditions while ensuring the operation bounds in order to guarantee the battery reliability and durability. Most of the control algorithms found in the literature...
The paper presents a sensorless disturbance detection procedure that was done on a five phase induction motor with third harmonic injection. A test bench was developed where a three phase machine serves as disturbance generator of different frequencies. The control of the machines is based on multi scalar variables that ensures an independent control of the motor EMF and the rotor flux. For disturbance...
In this paper, a sensorless field oriented control system of five-phase induction machine with the 3rd harmonic rotor flux is presented. Two vector models, α1-β1 and α3-β3, were transformed into d1-q1, d3-q3 models oriented in rotating frames, which correspond to the 1st and 3rd harmonic plane respectively. The authors proposed the linearization of the model in d-q coordinate frames by introducing...
This paper presents a fast and robust control system for a three-phase quasi-Z-source inverter (qZSI) connected to the grid. The topology combines two quasi-Z-source networks with a T-type inverter allowing to obtain AC voltages with multilevel characteristics and properties of the referred networks. To control this system a closed-loop current controller for the AC currents is proposed. The controller...
In many power electronic applications the request of short development time demands reliable simulation studies to prove the control concepts in early developments stages and avoid critical behavior in real application. Simulation studies are sufficient to prove the general behavior of a control code. However, the platform architecture of the target hardware influences control behavior and code stability...
