    High frequency electronic inverter 3kW resonant magnetron power supply for microwave heating system

    High frequency electronic inverter 3kW resonant magnetron power supply for microwave heating system


    High power, high voltage, low voltage, high frequency electronic inverter


    Product introduction:
    Design and production of high power, high voltage, low voltage, high frequency electronic inverter
    High voltage grade: 3.0-30KV 2A
    Low voltage grade:5-24V 1000A
    Single-machine capacity grade:2.2-60KW
    Core technology
    1. The main design technology of high power resonant design technology
    2. Electric power transmission technique of high-voltage and high-frequency within 30KV
    3. The core control technique of resonant power convertor with high reliability has been acknowledged in the full range LLC resonant converter and the control method and its characteristic is a. electrolytic capacitor without energy storage in loop circuit of main convertor can adopt to any natural environment and grid environment;b. Under busbar voltage (5%-100%) condition of sine waveform output by AC/DC rectifier electronic switch of LLC convertor achieve zero voltage on and off status within full voltage range.This is the technical barrier which can not be exceeded by present contact and non-contact charging station.
    4. LGBT drive technology mentioned in (Passive isolation drive)(patent unpublished),same to EXB840 of Fuji,JP.
    The advantages:a. The full-bridge conversion only need a pair of power supply,b. drive signal frontier delay 700Ns and lag delay 200nS,fit for10KHZ-150KHZ(including the charging delay of grid damping resistance and 25cm PCB wiring delay,c. it can not check (block)pulse width less than 500nS, d. the 1200V tube driving current range:80A-480A,corresponding converter power:10KW-60KW
    Product covering field:
    Industrial microwave industry, industrial UV lamp field, Electromagnetic induction heating industry, laser power supply industry, ultrasonic power supplyindustry, automobile charging station industry (including wireless charging ), electroplate andelectrolysis.

    Technology platform:All products apply for LLC resonant power convertor technology
