Nonlinear optimal control for VSI-fed six-phase PMSMs

AIP Conference Proceedings, 2023
In this article, a nonlinear optimal control approach is developed for voltage-source inverter-fed six-phase Permanent Magnet Synchronous Motors which can be used in electric vehicles' traction. The dynamic model of the VSI-fed six-phase PMSM undergoes approximate linearization around a temporary operating point that is recomputed at each time-step of ...

A six-phase bi-directional interleaved converter

2016 International Symposium on Electrical Engineering (ISEE), 2016
This paper investigates the operation of a bi-directional interleaved converter. The DC-DC converter can operate both as a buck and a boost converter as per operating requirements. Design methodology for the converter operating in either modes is presented in detail.

Six‐phase heating™: The new power tool

Remediation Journal, 1999
AbstractThe removal of dense non‐aqueous phase liquids (DNAPL) in‐situ remains one of the remediation industry's toughest burden. Numerous treatment methods have been applied in an effort to deal with this problem, most requiring many years of continued application to produce even marginally successful results.

A dualband six-phase voltage-control oscillator

2018 7th International Symposium on Next Generation Electronics (ISNE), 2018
The voltage-controlled oscillator (VCO) by using single-ended delay cell architecture has the advantages of low power consumption, small chip area and large output swing. However, the conventional even-phase outputs ring-type VCO cannot be implemented by single-ended delay cells.

Scalar control of six-phase induction motor

2017 Open Conference of Electrical, Electronic and Information Sciences (eStream), 2017
Paper presents MATLAB Simulink model of symmetrical six-phase motor controlled by six-phase frequency converter and analyses its dynamic performance in volts per hertz mode. The new control blocks were elaborated, because Simulink library has no blocks for six-phase motor control.

Mathematical Model Research of Six-Phase PMSM

Advanced Materials Research, 2012
The six-phase permanent magnet synchronous motor (PMSM) is designed with two sets of Y-connected windings phase shifted by 30 electrical degrees. Two mathematic models of six-phase PMSM are established by different methods, which are based on dual d-q transformation and decoupling vector space respectively.

The Six Phases of Court Proceedings

2017
INTRODUCTION TO THE PRE-ACTION STAGE The ‘pre-action phase’ covers the period from the occurrence of the contested issue or relevant ground for complaint to when that matter produces formal civil proceedings. Such fees are prohibited in respect of personal injury claims. Compliance with this ban will be monitored by relevant regulators.

The six-phase twisted-ring counter circuit

2004 24th International Conference on Microelectronics (IEEE Cat. No.04TH8716), 2004
The behavior of the Six-Phase Twisted-Ring Counter (6P-TRC) circuit is analyzed. The circuit demultiplexes the input signal into six individual phased clock signals that exercise a phase difference equal to the half period of the clock. A tree-like structure is built by applying the phased outputs of the circuit to the clock inputs of six replicas of ...

Single-phase to six-phase voltage converter

Международный научный журнал «Инженер»
This paper presents a novel circuit for converting a single-phase power supply into a stabilized six-phase voltage system. The proposed converter is based on a three-limb transformer with six secondary windings connected in a hexagonal configuration and two primary windings connected in series opposition. Each primary winding is shunted by a capacitor,

Transient analysis of six-phase synchronous machines

2008
Six-phase synchronous machines have been used in the past for high power generation, and presently are being used in high power electric drives and in ac and/or dc power supplies. This thesis presents a mathematical model for investigating the transient performance of a six-phase synchronous machine, and develops a model for the simulation of such ...
