    Power electronics generally deal with the control and conversion of electric power.It is the application of solid state electronics.
    The basic for power electronics is electronic devices- power diodes, transistors, thyristors, triacs, GTOs, MOSFETs and IGBTs. It is important to know the characteristcs and operation of these devices. If you know this, operations of rectifier, bridge converter, chopper, inverter etc will be quite easy. You can also expect some numerical questions.

    Ok in order to study power electronics you have to understand how the devices used will perform at different set of voltages.

    Take an example of a normal diode, ideally it is short circuited in forward bias and open circuit in reverse bias.

    Next, when you check in practical applications you will have a 0.3V for germanium diode and 0.7 for selenium as the breakdown voltage.

    So study the characteristics and understand the behavior in different conditions for AC , DC , Saw tooth and Step Voltage.

    If you can understand these basics you will easily understand all the other applications and theory of power electronics.

    Post particular questions here, so that I can answer them for you.

    There are couple of books ,

    First go through Salivahana Electronic Devices and circuits book, and study some basics about diode and transistor dont spend more than 2 days here.

    Next go for , PS Bimbhra all the chapters, except drives. This books is awesome for thyristor working and inverters.

    Next go for Kanchandani for drives. If you do all these you will master power electronics.

    I dont know in which year of Engineering you are in , if you havent done with the power electronics lab then understand all the experiments and working of each and every circuit. To understand this you will have to understand the working principles (practical) of all the devices involved. Believe me you will learn a lot.

    After this, you can go through all the formula involved in calculations.
