1) Types of Converter used in an EV are: AC to DC Converter: It converts Alternating current to Direct current.Commonly used as rectifiers.Widely seen in battery charging. DC to DC Converter: It converts unregulated DC input to regulated DC output. They are 3 types i.e. Isolated,Non Isolated and resonant converters.They…

1)Speed control DC Motor using BJT H-Bridge:-  Description The Bipolar Junction Transistor (BJT) when used for power switching applications, operates as an IGBT. When it is conducting (BJT operating in the saturated region), a forward voltage Vf is developed between collector and emitter (in the range of 1 V). Therefore,…

1) Energy required for braking for different drive cycles can be calculated in excel sheet: 2) An electric motor can’t develop braking torque at a high speed similar to starting, because the Braking Torque of an EV Motor is not as high as the Acceleration Torque. Therefore Regenerative braking is cannot happen…

Part A: 1) How Much Do Airplanes Weigh? To this day it still amazes me how something that can weigh so much can even get airborne! Some of the weights that airplanes take off are staggering. In this article, I want to look at some of the most recognizable aircraft and break down what they weigh and what makes up the weight.…
