Power saving =30 Percent Stable and continous working Using high-power MOSFET, the equipment efficiency=85 PercentThe solid state high frequency equipment mainly used for HF welded steel pipe line.It is a typical AC-DC-AC variable frequency structure. Rectifier adopts 3-phase bridge style thyristor phase-control rectifier circuit, DC side adopts inductor, capacitor to compose LC filter which meet the working requirements of voltage type inverter. The voltage type inverter adopts modularization parallel structure to extend power supply power, each inverter module is single phase MOSFET bridge style circuit connected with series resonance tank circuit by H.F. matching transformer. On one hand, the matching transformer realizes power combination and impedance matching on the other hand it realizes electric isolation of load and power supply. To put effective and swift protection on over-current malfunction of voltage type inverter, our company introduces special and stable over-current protection circuit which guarantees safe and stable running of inverter.
