Soft Starter (Soft starter) is a set of soft start, soft stop, light-load energy efficiency and versatility protection in one of the motor control equipment. Achieve no impact throughout the startup process to start the motor and smooth, and can be adjusted according to the load characteristics of the motor during startup of various parameters, such as current limit, start time and so on. Soft starter (soft starter) is a set of novel motor control motor soft start, soft stop, and a variety of energy-saving light load protection functions in one, foreign called Soft Starter. Soft starter with three opposite parallel thyristors as regulator, between the power supply and the motor stator to access. This circuit such as a three-phase full-controlled bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor converter agent gradually increased, gradually accelerate the motor until full conduction thyristor motor to work on the mechanical properties of the rated voltage, to achieve a smooth start to reduce the starting current, avoid starting overcurrent tripping. Until the motor reaches the nominal number of revolutions, the end of the boot process, the soft-start automatic substitution thyristor converter has the task of using the bypass contactor for the normal operation of the electric motor to provide the rated voltage to reduce heat loss maintenance thyristor converter, extend the life of the soft starter, improve their efficiency, but also make the grid to avoid harmonic pollution. Soft start soft stop function also provides the inverter, soft start and soft stop opposite process, voltage decreases, the number of rotations gradually decreased to zero, to avoid torque shock caused freewheel. The main role of the inverter: The inverter is the use of power semiconductor devices will be the role of the on-off frequency to another frequency power conversion power control device. Can be divided into AC - AC inverter, AC - DC - AC inverter. AC - AC inverter directly to alternating current into alternating current frequency and voltage are variable; AC - DC - AC inverter is first rectified alternating current into direct current by the rectifier first, and then through an inverter to the DC Current and voltage can be changed into a frequency ac inverter price | Songzi converter | Yueyang Ohm Electric offers from Yueyang Ohm Electric Co.
