Title: Electrical Losses in SemiConductior Devices during Control of the Processes
Keywords: AC voltage stabilization, Electrical losses, Semiconductor devices, Phase control, Frequency dependence

Abstract: Electrical losses are significant for the normal work of semiconductor devices (diodes, transistors, thyristors, symistors (triaks), dynistors, etc.). In this paper, the phase control of a thyristor circuit activated by an AC voltage source with varying frequencies is analyzed. The formulas for the average Iav and the effective IRMS values of the current and the average power Pav as functions of the firing angle α and a frequency f have been worked out. The criterion for determining the maximum admissible firing angle α of the thyristors in the case of different frequencies has been suggested. The paper finishes with conclusion remarks for the AC supply voltage stabilization in phase control of the average value of the AC current flowing through a load.
