For this purpose we are designing a model that can control the speed of a DC motor and to control its speed different techniques can be used. Here we are designing a dual converter using thyristors to control the speed of our DC motor by controlling its firing angle.Saniya Naseem Zunjani...
The converter must also be highly efficient as it results in significant cost savings and reduced thermal solution. GaN based 1-MHz Dual Active Bridge Converter MATERIALS AND METHODS We are using Simulink to simulate and demonstrate this project. We have a DC source and we are converting it ...
Easy to configure with Windows®GUI or direct by MCU Multiple I/O pins for control and status Secure AES128 encryption Firmware can be field upgradable via UART Compact surface mount module: 22 x 12 x 2.4 mm (BM78SPPS5MC2) 15 x 12 x 1.8 mm (BM78SPP05MC2) Castellated surface mount ...
GaN based 1-MHz Dual Active Bridge Converter MATERIALS AND METHODS We are using Simulink to simulate and demonstrate this project. We have a DC source and we are converting it into AC using an inverter. This AC voltage is increased or decreased using a transformer and it is given to the ...
the12thyristors130function as switches and are arranged to interconnect either the three-phase utility line112or the battery122to the rectifier. The six thyristors130aconnected to the utility line112would normally be used in a three-level converter. In addition to selectively connecting the utility ...
Thyristors are used for the switching operation which is controlled by the pulse generator. Open loop dual converter technique proposed in this paper. The Four quadrant operation of both the single-phase dual converter and the three-phase dual converter has explained using the Simulink model. All ...
THYRISTORSMATLAB (Computer software)SIMULATION methods & modelsWith recent advances in power electronics, dual converter power supply based electric variable-speed drives are significantly used in many industries uses. Power electronic motor drivers are becoming able to efficiently read...
It incorporates cosine firing technique using integrated circuitry. A speed loop with PI controller maintains the desired speed irrespective of the load variation on the motor. An inner current control loop again incorporating a PI controller, protects the thyristors from overcurrents and also provides...
thyristors P and N of the dual converter. The terminals A, B of the dual converter are connected to the armature of motor M. The VAR reactive power on the primary side of the transformer is sensed and detected by a VAR sensor 13. A VAR control circuit 14 responsive to VAR sensor 13 ...
Overvoltage protection circuit for thyristors in frequency converter - has dual-primary transformer to reduce restrictions on thyristor turn-off voltsThe protection circuit has a transformer (10) with two separate identical primary windings (W1,W2) each in series with one of two thyristors (21,22)...
