Controlled Rectifiers

After completing this chapter, students should be able to do the following:

•  Model SCRs and specify their model parameters.

•  Model voltage-controlled switches.

•  Perform transient analysis of controlled rectifiers.

•  Evaluate the performance of controlled rectifiers.

•  Perform worst-case analysis of resonant-pulse inverters for parametric variations of model parameters and tolerances.

11.1  INTRODUCTION

A thyristor can be turned on by applying a pulse of short duration. Once the thyristor is on, the gate pulse has no effect, and it remains on until its current is reduced to zero. It is a latching device. PWM techniques can be applied to controlled rectifiers with bidirectional switches in order to improve the ...
