Dual Converter Control of DC Separately Excited Motor

Dual Converter Control of DC Separately Excited Motor: A Dual Converter Control of DC Separately Excited Motor (Fig. 5.35) consists of two fully-controlled rectifiers connected in anti-parallel across the armature. For power ratings upto around 10 kW, sigle-phase fully-controlled rectifiers can be used. For higher ratings, three-phase fully controlled rectifiers are employed. Rectifier A, which […]

DC Motor Braking Methods

DC Motor Braking Methods: The need for electric braking was explained earlier, the motor works as a generator developing a negative torque which opposes the motion. Three types of DC Motor Braking Methods are Regenerative braking; Dynamic or Rheostatic braking; and Plugging or reverse voltage braking. 1. Regenerative Braking: In regenerative braking, generated energy is supplied […]
