JQM series switching power amplifiers embody the latest MOSFET technology, output power from lkVA to 70kVA, a full range of air cooling. JQI series adopts the latest generation of IGBT soft switching resonance technology, the output power is from 5kVA to 500kVA, the power margin is large, the conversion efficiency is high, and the electromagnetic compatibility is good. The power amplifier is composed of a logic unit, a power unit and a control unit, and has the outstanding advantages of intelligent control, stable and reliable, flexible configuration, high efficiency and energy saving, compact structure and convenient maintenance. The power amplifier uses several power units to work in parallel. The method is flexible and flexible. Users can increase or decrease the power module and power amplifier power module according to the actual required capacity. It is not necessary to replace the rack. The system uses a new generation of IGBTs and adopts soft-switching resonance control. Technology, power margin, (single effective peak power is greater than 20kVA), high conversion efficiency, good electromagnetic compatibility. It promotes the advancement of electric vibration system to high power, large excitation force and intelligent direction; and provides reliable guarantee for the development of national defense and cutting-edge technology, and enhances the competitiveness of China's electric vibration test equipment in the international market.
