? What is Power Electronics

Power electronics is a field of electrical engineering that deals with the conversion and control of electrical power from one form to another. It involves the design and implementation of electronic circuits and systems for efficiently controlling and manipulating electrical energy, typically in the form of voltage and current, to meet specific requirements in various applications such as motor drives, renewable energy systems, and power supplies.

?What is Pulse Width Modulation (PWM) and how is it used in Power Electronics

Pulse Width Modulation (PWM) is a modulation technique used in power electronics to control the average voltage or current supplied to a load. It involves rapidly switching a power semiconductor device (such as a MOSFET or IGBT) on and off at a high frequency while varying the width of the on-time or duty cycle. By adjusting the duty cycle, the effective voltage or current delivered to the load can be controlled. PWM is commonly used in applications like motor control, voltage regulation, and inverter systems for variable speed drives and voltage conversion, as it provides precise control over the power delivered to the load while minimizing energy losses and achieving high efficiency.
