Abstract:
Controlled thyristor rectifiers provide regulatable output d.c. voltage, current and power necessary in many power application by phase control of the moment of turning on the devices. But at the same time the power factor in respect to the supplying mains is decreased that leads to an additional loading of the system for generation and distribution of electrical energy. That is rather important nowadays taking into account the struggle against the global warming. On the other hand the phase control causes increased pulsations of the rectifier voltage, measured by the ripple factor. To remove the undesirable ripples inflicted by the phase angle regulation larger filters are required. Different rectifiers behave differently in respect to the power and ripple factors. The aim of this article is to study the most commonly used types of controlled thyristor rectifiers and to clarify, and compare the information concerning their power and ripple factors.
