Freewheeling Diodes for High Performance Inverter Systems

Posted on 25 June 2019

      The engineers at Proton-Electrotex developed freewheeling diodes to operate at the reverse recovery process with high change rate of reverse recovery current (dIrrm/dt), and high power supply reverse voltage (VR) by means of proton irradiation technology, sintering technology and implementation of n’-buffer. The diodes are designed to be used as reverse diodes [...]

New Fast Thyristors for Frequency Converters of Induction Heating and Metal Melting Units

Posted on 20 June 2019

  Proton-Electrotex developed and started mass production of the thyristors TFI393-2500-28 with the 100 mm diameter of semiconductor element. This thyristor will allow to receive new advantages while projecting the invertors in the induction heating and metal melting systems by means of increasing the commutating power on about 50% in comparison with its closest competitor [...]

Methods of Current Measurement in Mid-Frequency Power Circuits

Posted on 14 March 2019

      Fast-changing power current precise measurements are very important in modern measuring equipment for power semiconductor devices. It is quite important for converter equipment as well, since improved control algorithms are used there, which require knowledge of instantaneous current value in a certain period of time. By Alexey Poleshchuk, R&D Center, Proton-Electrotex JSC [...]

Graphs of temperature-dependence of back saturation current for a thyristor Т243-500 (continuous curves) which conforms to 2 reverse voltage values V. The point graph corresponds to dependence Is(T), calculated by the formula (20).

Modeling of Temperature Dependence of Power Semiconductor I-V Curves

Posted on 10 April 2019

              The I-V curve is the most important parameter of power semiconductors (PSD), since power semiconductor output capacity and efficiency depends upon it to a great extent. Many publications are devoted to the analysis of the physical phenomena determining I-V curves of power semiconductor devices (e.g. the monographies [1, [...]
