LECTURE NOTES ON POWER ELECTRONICS

Power Electronics is a field which combines Power (electric power), Electronics and Control systems. Power engineering deals with the static and rotating power equipment for the generation, transmission and distribution of electric power. Electronics deals with the study of solid state semiconductor power devices and circuits for Power conversion to meet the desired control objectives (to control the output voltage and output power). Power electronics may be defined as the subject of applications of solid state power semiconductor devices (Thyristors) for the control and conversion of electric power. Power electronics deals with the study and design of Thyristorised power controllers for a variety of applications like Heat control, Light/Illumination control, Motor control, AC/DC motor drives used in industries, High voltage power supplies, Vehicle propulsion systems, and High voltage direct current (HVDC) transmission.
