see the opening and shutdown in the output of the bridge arm points available
in three different level, turn on and off in output point of the bridge arm
available in three different level in the following table:cell phone jammer can
be conveniently fixed to the tripod. three-phase inverter bridge arm consisting
of three-phase inverter composed of three bridge arm, according to the
three-phase bridge arm, according to the three-phase bridge arm of U, V, W,
different combinations, different combinations, and ultimately available to the
three-level inverter = 2733 switch mode. three o'clock level inverter output
voltage and filter output voltage map picture shows the point level inverter
output voltage and by the filter output voltage waveforms of the motor. picture
shows the point level inverter output voltage and by the filter output to the
motor voltage waveforms before the filter, the output voltage harmonic
distortion 29% filtered down to about 4 percent before the electric filter, the
machine's current harmonic distortion can be reduced from 17% to about 2 percent
three-point level inverter main circuit of three-point-level inverter main
circuit structure of three-level voltage source inverter output voltage,
three-level voltage source inverter output voltage and current waveform in
Figure protect the common mode voltage limiting circuit limiting circuit M
reactor Figure 8-10 three-level inverter shown in Figure 8 -9 to the main
circuit diagram of three-level variable products,cell phone jammer is
ecologically friendly. the rectifier circuit to the main circuit of the
three-level variable product structure diagram, rectifier circuit 12 pulse
three-level converter products main circuit structure diagram red diode pulse as
shown in Figure rectifier structure. cell phone jammer is of steel
frame
Inverter part of the power devices can be red diode structure. inverter
part of the power devices can be IGCT, the freewheeling diode freewheeling diode
integrated in the IGCT IGCT switching frequency of the switching frequency is
about 600Hz. common-mode reactor. integrated in the switching frequency and
inverter for about accommodated separately accommodated separately, using a long
cable between the transformer secondary winding and the rectifier bridge input
inverter, its main function is to bear the total mode voltage and limit
high-frequency leakage current cable longer,cell phone jammer can be used
indoors and outdoors. its main function is to bear the common-mode voltage and
limit high-frequency leakage current due to the low impedance of the output
filter capacitor, the motor to withstand the common mode voltage is very low due
to the output The low impedance of the filter capacitor, the motor withstand
common-mode voltage is very low, common-mode voltage is shared by the input
transformer and inverter voltage shared by the input transformer and
inverter.
