This paper presents the issue of the control units used for tuning of Petersen coil. Utilization of specific algorithm is given by certain application assumptions. Generally, it is possible to say that all algorithms can contribute to reducing of the fault current size. The size of the fault current is different depending on the adverse effects and the algorithm used. This also influences the time...
An LC3L type Isolated bidirectional dc/dc converter is analyzed, including the effect of a high frequency transformer by using ac complex circuit approximation. Its solution is derived and is used to obtain the characteristics of the proposed converter. The analyses show the comparison of voltage gain with T-equivalent transformer results in introduction of magnetizing and leakage inductance at conventional...
Z-Source inverters can overcome some of the limitations, inherent in traditional Voltage Source and Current Source Inverters and can provide boosted outputs. Most of the literature on Z-source inverters deals with 3-phase or 1-phase bridge inverters. This paper proposes a Single-Phase Z-Source Push-Pull Inverter topology. This scheme has several advantages compared to basic Z-source full-bridge inverter...
The windup phenomenon caused by the current limitation and PWM voltage regulation in the brushless DC motor (BLDCM) double PI loop speed regulating system has been investigated. And the anti-windup controller has been applied to suppress the relevant windup phenomenon. The simulation illustrates that the anti-windup controller make the BLDCM speed regulating less overshoot and quickly dynamic response...
In order to solve the stability problem caused by the parameter mismatch of filter inductance for a conventional predictive current control, a predictive current control method based on on-line parameter estimation of filter inductance is proposed in this paper. The average filter inductance value is calculated in each cycle of grid voltage by means of the average inductance model and phase-locked-loop...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
