一、Brief Introduction about Solid State High Frequency Heating Power

Adopting new style MOSFET fast recovery diodes, composing switch device, circuit topology adopts mixed connective structure, avoiding the disadvantages of the simple series and simple parallel, exerting their advantages. HRGP series solid state high frequency power includes five parts: rectifier cabinet、transformer、inverter、operation station、water cooling system.

Input voltage：380V            Input frequency：50～60Hz

Output power：50～400kW       Output Frequency：100～450kHz

二、The character of solid state high frequency power

◎Output ripple ratio is low, welding is no spark, quality is good, power output steady, welding line is liner. As preferred for high precise welding pipe

◎Efficiency can reach above 85%. Energy-saving is obvious. Adopting advanced VZS technology, eliminating the switch loss of power devices, cooling water usage is little..

◎Safety without high voltage, inductor no spark for steel pipe special circuit of the cells, making inductor to produce proper voltage, avoiding spark between inductor and steel tube.  

◎Circuit Simple and Installation Convenient Applying multiple parallel resonance circuit. The lines between rectifier cabinet and invert cabinet is not more than 10. The lines between rectifier power and operation station are very small.

◎Protection Complete, Maintenance Convenient The entire equipment has all kind of protection measure, improving device’s stability and reliability by the greatest extent. All alarm information is sent to control board and PLC for processing.

◎Harmonic interference is little, no pollution to power grids Adopting low voltage resonance technique, some matched well filter network are designed in circuit, making solid state power low-harmonic at full power running.

◎Reliability High and Running Steady Technics arrangement is rational, design parameter are exact

◎Maintenance Convenient User can maintain is self. Person with repairing electron tube after training, can absolutely mend or maintain devices solely.

◎All types of control board’s modules are general without adjustment when changing
