Course description

Power Electronics is power conversion and control from one form of power (energy) source to a desired form by using power semiconductor devices wherein these devices operate as switches. This course provides a basic knowledge of power Electronics device characteristics and circuits for the control and conversion of electrical power with high efficiency .

Syllabus

Course description

These converters can change and regulate the voltage, current, or power; dc-dc converters, ac-dc uncontrolled and phase controlled rectifier circuits, dc-ac inverters, and ac-ac cycloconverters. Applications include electronic Switching power supplies, motors, heaters system, and renewable energy systems. Analysis, design, and operation of power electronic circuits will be considered by simulation software.
