causing an increase in the current flow angle and a reduction in the mains current harmonics, with the steady-state constant length of the switched-on intervals, which are the same in all the phases, defining the mean power flow of the system and being used as a control variable for contr...
Three-phase power control switch for Low-Voltage Alternating Current and any type of load imbalance between phases, which controls the power demanded by the installation in which it is connected, with satisfactory precision and response time, whatever the load imbalance between phases. Its operation ...
The paper considers integration of multiphase (more than three phases) machines and converters into a single-phase charging process of electric vehicles (E... I Subotic,N Bodo,E Levi - 《IEEE Transactions on Power Electronics》 被引量: 8发表: 2016年 Single-phase and three-phase compatible is...
we need to analyze these types of errors. The answer to the question of which improvements come first need not be “pre-analytical”, or “analytical”, or “post-analytical” – it should be all three phases at once.

The mathematical model was used to control a 140-kW regenerative VSC. The synchronous reference-frame model was used to define feedforward signals in the current regulators to eliminate the cross coupling between the d and q phases. It allowed the reduction of the current control loops to first...

methodologies such as statistical process control to optimize production on the fly by tweaking various aspects that, to date, have been onerous, manual adjustments. For example, changing the setpoint values or even the whole process sequence of a machine could be done without any human involvement...
harmonic currents which in such a system would be otherwise difficult to control. The techniques developed in this paper can be generalized for the control of an induction machine with an arbitrary number of phases 展开 DOI: 10.1109/28.464525 年份: 1995 ...
According to the digital control system and method, only three phases of input current and output voltage need to be sampled, the calculation of the control amount is simple and takes a short time, the unity power factor of the circuit is achieved, and harmonic pollution is small....
