A DC motor connected to a switch-mode dc-dc converter goes into regenerative braking mode. The average current being supplied by the dc motor is 20 A. In the equivalent circuit of the dc motor, Ea=103 V, Ra=0.19 Ohms, and La=4 mH. Calculate the average power flow into the converter. Round answer to the nearest whole number.

The correct answer is "2524 W".

Explanation:

The given values are:

Ia = 20 A

Ea = 103 V

Ra = 0.19 Ω

La = 4 mH

According to KVL,

⇒

On substituting the given values in the above equation, we get

⇒      

⇒      

⇒      

Now,

The average power flow into the converter will be:

⇒

On substituting the given values, we get

⇒    

⇒
