Structure and technology:

HF-15—70AB machines, series oscillating circuit is used, after oscillating circuit, power is output through high frequency transformer, and then there is low voltage and large current going through the induction coil.

In HF-15A/AB, HF-25A/AB machines, using MOSFET and IGBT components, our first generation current inverting control technology is adopted, these machines are characterized by simple structure, high reliability and low price, and they are easy to use and repair, So these machines are used most widely now both at home and abroad.

HF-25ABD,HF-35AB,HF-45AB have the same structure and same technology, IGBT module and our second generation inverting control technology has been used, that is the dual control and inverting technology. Output power and oscillating frequency are controlled independently. We use IGBT components and high frequency voltage regulate control circuit to control the power and we use IGBT components, series oscillating and automatic tracking circuit to reach soft switching in the inverting course, all these make the machine to be more reliable and make the machine possible to work continuously with 100% duty cycle.

on the basis of soft switch technology, voltage regulate circuit is used to control both the voltage and the current of the IGBT inverting module. By this new technology, the reliability of IGBT is raised greatly and let these machines working even more reliably than the first generation machines at large power output level.

Due to the adopting of advanced technology, HF-25ABD,HF-35AB,HF-45AB machines are characterized by larger frequency range, smaller size, water cooled transformer, higher reliability and lower repair cost.

Third generation technology is adopted for HF-70AB machine with even larger power, based on the second generation technology , soft switching of the IGBT is improved both in the voltage regulate circuit and the inverting circuit to ensure machines working smoothly at high frequency and high power. Because the oscillating capacitor is connected with the primary coil of the high frequency transformer, so this machine is low cost compared with others.
