2.Digital switching power amplifier
The system uses a sinusoidal pulse width modulation technology
digital power amplifier. Its working principle is: the use of
high-frequency switching capability MOSFET FET, the controller
input low voltage signal is amplified and revert to the original
signal by a digital circuit, and then output to the shaking table
moving coil lines, pushing shaker table movement. The main
components of a digital power amplifier: Front control, power
amplifier modules, protection circuits, power section and
electrical cabinets. The modular design of the system is driven by
a small thrust, the thrust and high thrust series shaker. The
output range of the power amplifier is 1kVA ~ 300kVA. System
