As we all know, thyristor module is short for crystal thyratron, it is also known as silicon controlled rectifier, sometimes also called silicon controlled rectifier. Thyristor module is made up of PNPN four layers of semiconductor structure, it has three pole: anode, cathode and gate. Thyristor module has the property of silicon rectifying device, can work under high voltage, high current conditions, and its working process can be extensively applied in the control, controlled rectifier, the ac voltage regulator, non-contact electronic switch, inverter and variable frequency electronic circuits. Today, small make up, and everyone see thyristor module in the dc motor control mode is how: first, to make the motor and reversing, requires the thyristor module control circuit makes the rectifier output voltage can be added to the motor reverse, or added to the voltage can reverse excitation circuit. Contactor) can be used to make motor reverse voltage, this approach does not need to circulation control, control is simple, cheap, often use. Reversal of the motor and variable speed, fast response, load change also requires quick recovery to the original speed, therefore, hope in the inverter running when the energy feed to the power of motor rotor. Second, using thyristor device to ac power to dc power supply, depending on the number and nature of the load circuit phase, will produce different pulse current. Thyristor rectifier power supply module in motor racing or light load motor current intermittent special phenomenon would appear, had a great influence on motor mechanical properties. When the current is interrupted, thyristor rectifier power supply module motor ideal no-load speed increases, the electric mechanical properties show the soft, changes of load torque on the motor axis is small can cause the great change of motor speed. So, dc motor power by thyristor controlled rectifier circuit, in order to improve the motor running situation, make it always work in feature harder area, most of the series reactor in the dc motor load, when no load or light load, also make the motor work in continuous area in current. This is thyristor module in the control of a dc motor, hope to be of help! Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, MTC thyristor modules, solid state relay module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, provide affordable, quality and reliable electronic components.
