Product Description
HVFS Series of High Voltage Frequency-Converting Soft Starter


1. Soft start function: Starting current less than rated current, repeatedly start allowed.
2. Direct high voltage in-out power distribution: DLHVF high frequency-converting speed regulator is appicable for normal AC induction motor. It directly input and output high voltage electric power. No transformer is needed. The device occupies little area.
3. No harmonic input: HVFS device has utilized the phase shift multi-rectify technology, the voltage and current harmonic is low. There is no need to use harmonic control devices in the input progress, no pollution to power system.
4. No harmonic output: HVFS device output standard sine waves, the voltage and current harmonic is low. No harmonic control device is needed in output progress. It will not increase the motor noise and will not generate additional stress.
5. High security level: HVFS is designed following China high voltage peremptory norm, high voltage primary circuit and control circuit are connected by optical fiber.
6. Perfect protection and fault alarm design: HVFS has perfect system protection and power unit protection function. And after protection it will auto record and simulate the fault conditions. The fault record includes protection operations, starting and lasting time which can help the analysis and define of fault.
7. Great flexibility: HVFC device is real-time controlled by PLC(programmable Logic controller). The control type settings can be convenient changed in human-computer interface. Variable standard communication protocol convenient for communication with center-control system.
8. Convenient installation, commission and maintenance: Drawer-type power unit, connect assembly for power unit and external wire. No manual connection needed and convenient to replace.

Unique features:

Waveform digitization direct synthesis adaptive technology:
HVFS Wavegenerator utilizes single-chip FPGA with certain algorithm to obtain discretization frequency and controllable amplitude 3-phase wave status, then compare to delta carrier in different phase and generates wave digital signal to control the power units in same phase to output fundamental wave in same amplitude and phase. The electric angle of carrier which connects every unit is staggered to implement multilevel superimposed waveforms and greatly enhance the reliability of the control system.

Low voltage overall commission function:
HVFS can utilize low voltage control power to do high voltage frequency-converting soft start function test. User can commission and maintain the device without high voltage power or frequency-converting. Therefore the commission and maintenance time is significantly reduced.

Advanced fault self check technology
HVFS device will online check all system and every power unit before starting. The check can be detailed to status of each IGBT chips, so that it can assure the device is in good condition and make the preparation more smooth.

Drawer-type power unit, convenient to replace and maintain:
Power units in HVFS device are connected with main circuit by active and static contactor. In installation and cannibalization progress only two optical fibers need to be removed. No need to install and remove the screws in main circuit. Besides, all the main circuit is contacted in cabinet, assures the safe of operators.

Power unit DC voltage online test function:
HVFS will online check the DC bus voltage of each power unit and shows the measurement results in human-computer interface, so that operator can easily realize the working condition of each power unit's main circuit and progress detailed analysis.

Frequency-converting soft start technology
The starting current is very low in frequency-convering starting progress. No limit of starting times. After starting the frequency of motor will be back to 50Hz. No current impulse in starting progress.
