2, high voltage inverter speed saving principle
2.1 Working principle of high voltage inverter
The high voltage inverter is a power control device that converts the power frequency power supply to another frequency by the on-off action of the power semiconductor device. It changes the pulse width or amplitude of the pulse column according to a certain law to adjust the output and waveform, so as to achieve smooth changes in the motor voltage and frequency. 3. High voltage frequency conversion speed regulation system application
3.1 Composition of high voltage inverter
Senlan SBH series high voltage inverter adopts unit series multilevel technology, and adopts multiple low voltage frequency conversion power units in series to achieve direct high voltage output. It belongs to the “high-high” voltage source inverter, which has small harmonic pollution to the power grid, high input power factor, and does not need to use input harmonic filter and power factor compensation device. Meet the requirements of IEEE519-1992 international standard and GB/T14549-93 national standard for input harmonics. The output waveform quality is good, there is no harmonic caused by the motor additional heating and torque ripple, noise, common mode voltage and other problems, do not need to set the output filter
