Features :

•  The solid state H.F. welder adopts Germany IXYS company IXFN38N100Q2 38A/1000V high-power MOSFET and DSEI 2×61-12B 60A/1200V rapid recovery diode to compose series type invertible circuit.
• The solid state H.F. welder adopts modularization design with more compact structure which makes maintenance and high-power realization much easier.
• It has particular technology of bridge-divided over-current protection that guarantees equipment safety.
• It combines international advanced control method of same products, adopts advanced technologies like fixed angle phase-locking control, upper frequency limit/lower frequency limit lock-lost protection and etc. With these technologies, the equipments run more stably, more efficiently, more accurate and effective protections to the inductor short-circuit and open-circuit malfunction during pipe welding production.
• It has most advanced Electronic automatic load matching technology (PS+PWM control tech), it make machine working at best condition. Buyer doesn’t need change any parameter under induction/contact welding types.
• Line-in end of solid state H.F. welder does not need step-up /step-down rectifier transformer, compared with vacuum tube welder and parallel type welder; it has significant energy-saving effects (Under same welding condition, energy-saving ≥30% compared with vacuum tube welder).

 
Working principle of solid state H.F. welder Solid state H.F. welder main circuit structure is as follows fig.1; 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. 
Electronic automatic load matching technology of solid state H.F. welder Load matching is to make equivalent impedance of load equal to impedance required (R_N=U_N/I_N) to output rate power. Good matching is guarantee for output and stable working. The welder’s load’s equivalent impedance will change with changing of parts and cause load matching problem. If load is not matched, welder will not output rate power. When welder and load both are matches, i.e. welder also in best condition and best loading capacity. Now the ways to adjust load matching: adjust parameter after machine stops (induction size, diameter and resonant capacitor) or change parameter by step motor, not well. Our welder has Electronic automatic load matching technology, this technology can only use on Series welding machine which decided by its features, below figure is automatic load matching and output curve of voltage, current and power output. 

Advancements of Electronic automatic load matching technology

•  Buyer doesn’t need change any main parameter to get load matching based on different tube materials.
• Welder can guarantee rated DC current, adjustable DC current continuous liner.
•  AC Side power factor is high (>0.9 when load is 50%), when output equals DC power, input side current and harmonic current is minimum.
• Welder can get better efficency, 5% higher than same level welders.
• Buyer doesn’t need to change main parameter to get switching between induction/contact types.
• Auto matching range according to different working frequency, 100kW300kW welder: range 30%; 400kW800kW welder: range 40%; 800kW1200kW welder: range 50%.

For frequency more than 200kHz or other low cost application filed, vacuum tube high frequency power supply still has an irreplaceable position and wide application. 

Vacuum tube high frequency power supply adopts AC-DC-AC frequency variable structure. Convert power frequency AC voltage to adjustable high voltage DC voltage through the matching of 3-phase AC voltage regulation circuit, step-up transformer and high voltage silicon rectifier stack (3-pulse wave or 6-pulse wave). Oscillating circuit adopts high frequency large power vacuum tube to produce self-oscillation. Resonant circuit can adopt single circuit or three-circuit mode. 

The whole unit of equipment is composed of AC voltage regulation cabinet, step-up transformer, vacuum tube (Oscillator valve) oscillator cabinet which has tank circuit, circulation water cooling system, and console.
