Transistor frequency converter TFC
Frequency range of rational use of thyristors as main controllable device in frequency converters, generally does not exceed 10 kHz. Converters with frequency range from 10 to 66 kHz are usually build on basis of IGBT transistor modules and in the frequency range 200-500 kHz - MOSFET transistors. Converters of TFC type have two-tier structure of power circuit, consistent of controllable straighter and current inverter.
Converters are equipped with systems
• Digital control system ;
• polarization (for power magnetostrictive transducers);
• Internal self-diagnostic and protection;
• Visualization of parameters and the status of the converter.
