Question

8 full converter fed drive? Explain. A 230 V separately excited DC motor takes 50A at a speed of 800 rpm. The Ra =0.40 and the motor is controlled by a chopper with input voltage of 230 V and frequency of operation of chopper is 500Hz. Assume continuous conduction Calculate (i) speed at motoring operation for duty ratio 0.3 and 0.6 (ii) speed at braking operation at duty ratio 0.7​

Answer 1

Step-by-step explanation:

Schlieffen Plan, battle plan first proposed in 1905 by Alfred, Graf (count) von Schlieffen, chief of the German general staff, that was designed to allow Germany to wage a successful two-front war. The plan was heavily modified by Schlieffen’s successor, Helmuth von Moltke, prior to and during its implementation in World War I. Moltke’s changes, which included a reduction in the size of the attacking army, were blamed for Germany’s failure to win a quick victory.
