Operation with a Purely Resistive Load


Pages in this Section:


This chapter describes the operation of a single-phase fully- controlled bridge rectifier circuit with a resistive load. The operation of this circuit can be understood more easily when the load is purely resistive. The analysis in this page is based on the assumption that the SCRs are ideal controlled switches. It means that when the SCRs are ON, the ON-state drops are zero. In the OFF- state, the leakage current is assumed to be zero. The main purpose of the fully-controlled bridge rectifier circuit is to provide a variable dc voltage from an ac source.

The next chapter describes how the circuit behaves when the load has a reactive and a resistive component.
