5 Analysis of Controlled Rectifier Circuits
Traditionally, conversion of AC to DC voltages has been dominated by phase-controlled or diode rectifiers. Three-phase fully controlled bridge rectifiers are well suited for several power electronic (PE) applications that require a large current such as brushless excitation systems for aircraft generators, high-voltage AC-to-DC converters, and DC motor speed control systems [1–4]. The performance of a slip-ring induction motor can be controlled by a silicon-controlled rectifier (SCR) [5].
Different technologies [6] are used in the generation of large controlled currents in the kiloampere range. Microcontroller- and microprocessor- based control techniques and design of three-phase and single-phase ...
