Vibration Testing System Lab Equipment Improve Packaging Design with Slip Table
Digital switching power amplifier
The system uses a digital power amplifier with sinusoidal pulse
width modulation. The working principle is: using the
high-frequency switching capability of the IGBT FET, the
low-voltage signal input by the controller is amplified by the
digital circuit and restored to the original signal, and then
output to the moving coil of the vibrating table to promote the
electric vibration. Taiwan movement.
The main components of the intelligent high voltage power amplifier
are: front control, power amplifier module, protection circuit,
power supply part and electric cabinet. The system adopts high
voltage and small current output form, which reduces the power loss
during transmission and achieves effective and reasonable impedance
matching.
