Power Electronics is an important area of Electrical Engineering. It may be defined as the applications of solid-state electronics for the control and conversion of electric power. The amount of power handled may vary from a few watts to megawatts.

                                        
Power electronic systems are virtually in every electronic device. For example, battery charger of mobile devices (mobile phone, pda…); switch-mode power supply (computers, televisions,…); modern motor drives and important conditioning devices for power transmission and distribution systems (uninterruptible power supply, STATCOM, …).

Applications of Power Electronics Technology

In terms of commerce, the impact of power electronics is also huge. Sales of power electronics equipment exceed $60 billion each year and affect another $1 trillion in hardware electronics sales.

The Worldwide Electronics Marketplace

Major advances in power electronics technologies have been witnessed in the last decades. As power semiconductor devices improve in performance and decline in cost, power electronics technologies play a critical role in energy saving, storage and transmission and global industrial automation.
