TC520 3BSE001449R1 High Voltage Source Type Frequency Converter

TC520 3BSE001449R1 high-voltage frequency conversion speed control system, with high-speed DSP as the control core, using space voltage vector control technology, power unit series multi-level technology, high reliability, easy operation, high performance as the design goal, to meet the needs of users of various types of loads speed control and energy saving, and to improve the production process, belongs to the high-high-voltage source frequency converter. Its harmonic index is far less than the harmonic national standard of IEE519-1992, the input power factor is high, the output waveform quality is good, and there is no need to use input harmonic filter, power factor compensation device and output filter.

TC520 3BSE001449R1 controls the excitation current and torque current of AC motor respectively according to the principle of magnetic field orientation by measuring and controlling the stator current vector of AC motor, so as to achieve the purpose of controlling the torque of AC motor. It has large starting torque, fast dynamic response of torque, high precision of speed regulation, and strong capability of carrying load. The technology is suitable for belt conveyor, friction elevator and other occasions where power balance control is required.

TC520 3BSE001449R1 inverter is equipped with master-slave control function, and a master-slave control network can be formed between multiple inverters through the data bus. Set one of them as the master and the others as the slaves, the master collects the state information of each slave in real time and sends frequency and torque commands to each slave at the same time to realize the power balance and integrated control of each inverter. After detecting the unit failure, the unit can be bypassed within 100us, and the star-point drift technology is executed to keep the output line voltage balanced and maximize the voltage utilization.
