This example shows the operation of a current-controlled thyristor rectifier.Description A DC motor represented by a simplified RL-E model is fed from an inductive three-phase source through a six-pulse thyristor bridge. A pulse generator synchronized on the source voltages provides the trigger ...
The rectifier includes mosfet, transistor, thyristor or IGBT switching semiconductors. The current analysis unit includes inductance, especially saturable inductance or ferrite bead(s). An independent claim is included for the corresponding method of controlling the circuit....
A new current control method for three-phase phase-controlled thyristor rectifier that has an LCL filter is proposed in this paper. The proposed method is based on state feedback and tracking system. By using this method, the load current can be controlled with a minimum sensor and the load...
The performance of a PWM-controlled thyristor rectifier operating at unity fundamental input power factor in a PWM current source GTO inverter system for a high speed high horse power induction motor drive is analyzed. With the application of an energy rebound circuit in the DC link of the inver...

Average-value modeling of thyristor controlled line-commutated converter using voltage and current source formulations 来自 掌桥科研 喜欢 0 阅读量: 72 作者:H Atighechi,J Jatskevich,JM Cano Rodríguez 摘要: Line-commutated converters (LCC) can operate in both rectifier and inverter modes and are ...
A four-quadrant AC-fed converter for a DC machine drive using a single bridge thyristor fully controlled rectifier with GTO (gate turn-off) thyristor zero-current reversing switch is described. The circuit has the advantages of no circulating currents and very short current commutation time. Microp...
The control pulses for the sweep thyristor are obtained from the commutating inductor via a rectifier (11) and RLC circuit. The first peak from the commutating inductor charges a parallel capacitor (12) which discharges into a capacitor (14) in the RLC circuit. This latter capacitor ...
