Features reversible thyristor contactless synchronous rectifier machines depending on the control angle

Abstract

Techniques for calculating the characteristics of reversible thyristor rectifier for contactless synchronous machines, depending on the angle of thyristor control, are presented. Calculation of the protective circuits of thyristor rectifier is held at a zero control angle following the method of calculation of diode rectifiers. Changing thyristor control angle from 0 to 90 degree does not increase the maximum stress voltage on the thyristor. Calculation models of thyristor rectifier is conducted in the circuit simulation in a quasi-steady or transient operating conditions. The calculation models rectifier in transient modes of operation are limited to the number of variables, the current numerical values are recorded in the memory of the program, the calculation is performed at a frequency thyristor control the lower frequency power supply rectifier. The results of calculation models rectifier diode and transistor should be used in the comparative analysis of contactless synchronous machines exiters.
