TFi DIGITAL INDUCTION POWER SUPPLY Precision Power Converters for Heating Applications The TFi series of converters from Radyne offers a selection of power and frequency combinations suitable for most induction heating applications. Applications suited to the rugged, reliable and flexible TFi series includes: • Surface Hardening Joining Processes Shrink Fitting Wire Heat Treatment • Cable Preparation Crystal Growing Silicon Processing General Induction Heating Applications Radyne TFi Converters utilise high efficiency IGBT power semi-conductors with faster switching characteristics, ideally suited to inductuion heating applications between 3 - 50 kHz. The performance of the TFi series tuned output circuit can be matched to the working load by selecting the appropriate output tapping and amount of capacitance built into the converter to suit the required coil configuration. The compact design of the TFi series ensures that it can be easily installed into process lines or manufacturing cells. Alternatively the converter can be intergrated into the construction of a free-standing induction heating machine. CONSTRUCTION The complete range of TFi convertors is constructed using modular power transistor assemblies rated at 60 & 250 kW. By using one, two or more modules, an extensive range from 20 kW to 2000kW is available using a limited number of external cabinet sizes. Available with nominal output frequencies of 3, 10, 30 and 50 kHz the TFi range is produced in two versions suitable for both high and low impedance load conditions likely to be encountered in the majority of industrial process heating applications.
