2.Digital switching power amplifier

2.1 Overview

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 Specifications fully applicable to existing or new air-cooled or water-cooled electric vibration table.
