This 12 month program from Skill-Lync equips the student with the necessary knowledge required to perform the design and analysis of power converters used in electric and hybrid electric vehicles.
The law of conservation of energy, as we know, states that energy can neither be created nor destroyed but it can change its form from one to another. We can see countless examples in real life where this law is upheld, such as dams, vehicles, etc. But when we speak about energy usage, another term is used called Power. A popular misconception among people today is that the terms power and energy can be used interchangeably, which is not true. Energy is the total amount of work done, while power is how fast the work is done. In simpler terms, power is energy per unit time. Just like energy, power can be converted from one form to another. This process in which electrical energy is converted from one form to another is known as power conversion, and the device used for this purpose is called a power converter.
Being an electrical or electro-mechanical device, a power converter can be as simple as a transformer or a far more complex system. It can convert alternating current (AC) to direct current (DC) and vice versa, change the voltage and frequency of the current, or a combination of these two processes. The main purpose of a power converter is to convert the electrical energy to a form which is optimally suited for the user loads.
Initially, energy was converted in electromechanical converters. These converters were basically rotating devices and were not as efficient. However, with the development of more sophisticated technology such as power semiconductors, static power converters have found applications in various fields. Unlike rotating power converters, static power converters are smaller and lighter, and they provide better static and dynamic performance.
An ideal static power converter is able to control the flow of power with 100% efficiency, which is not possible. There are always some factors which affect the efficiency of not just power converters but the whole system. Nevertheless, engineers strive to develop power converters with as high efficiency as possible. At Skill-Lync, we are trying to provide insights and guidance to design and develop modern converters with advanced controls.

Power supplies for telecommunications applications may require high currents at low voltages. Design a buck converter that has an input voltage of 3.3 V and an output voltage of 1.2 V. The output current varies between 4 and 6 A. The output voltage ripple must not exceed 2 percent. Specify the inductor value such that the peak-to-peak variation in inductor current does not exceed 40 percent of the average value. Assume the switching frequency=500kHz.
Design a boost converter for DC drive with input voltage =250 V, input current = 200 A, output voltage= 400 V, switching frequency=50kHz. Calculate the ripple voltage and ripple current. Obtain the average state space model of the designed converter. Check for controllability and observability
