Transistor frequency converter TFC

img

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.

 

Advantages

 

Automatic frequency control;

uncritical load;

stepless adjustment of output power;

polarization system (for power magnetostrictive transducers);

self-diagnosis and protection;

Cost-effectiveness and high efficiency (0,9);

Small size and weight;

high reliability;

ease of operation and transportation;

forced air cooling;

Multifunction LCD display parameters and status.
