In this comprehensive study of thyristor control of dc drives, waveforms are used to illustrate the operation of thyristor converters and many examples are given. Topics include phase controlled and chopper drives; analog, digital, phase-locked-loop, and microcomputer
control techniques; computer analysis of drive systems; design procedures for input filters, proportional (P) and proportional-integral (PI) controllers; dynamic and regenerative braking in industrial drives and transit systems; power factor improvement in phase controlled converters; commutation techniques and design of choppers; terminal characteristics and protection of power semi-conductor devices; and hardware of some basic firing and control circuits. |
