Am. Zaki et al., MICROPROCESSOR-BASED SPEED CONTROL OF DC MOTOR FED FROM SEMICONVERTERSUPPLY, European transactions on electrical power engineering, 3(5), 1993, pp. 331-338
The tremendous progress in semiconductor technology has made solid sta
te DC motor drives suitable for many practical applications. In this w
ork a simple method for gate control of a semiconverter circuit feedin
g a separately excited DC motor is presented which is used to vary the
motor speed The transient as well as steady-state characteristic perf
ormances have been obtained theoretically using closed form solution a
nd experimentally using digital techniques. The required firing pulses
were generated digitally using a 16-bit microprocessor system. A set-
up for the experimental system has been designed and built in the labo
ratory. There is excellent agreement between the computed results and
those obtained from the actual set-up.
