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drive)(patent unpublished),same to EXB840 of Fuji,JP.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
