Basic concept of Power Electronics
• Power Electronics combines the fields of Electrical Power Engineering and Electronics Engineering.
Power Engineering Perspective
• It basically deals with the Generation, Transmission, Distribution and Utilization of Electrical power at a very high power level (up to KW or MW) with the important consideration that the efficiency must be as high as possible.
Electronics Engineering Perspective
• It mainly deals with the distortion less Production, Transmission and Reception of Electrical Signal at a very low power level (up to mille-watts. or few watts).
• Here, Distortion is the important consideration.

29
Present Trends in Power electronics
• Distributed generation and power quality are important future considerations.
• For very high-power applications, modularization will be expanding, provided the system cost, efficiency, flexibility and EMC are acceptable.
• For medium-power applications, the total system integration still leaves a lot of room for improvements in cost, power modules, control and sensing, passives, reliability and performance.
• Fast energy storage is required in numerous applications. At present, super capacitors seem to be the most promising solution for energies upto 5 kWh. In the next ten years, all other energy storage options will continue to be considered.
• Applications in power transmission include HVDC converter stations, Flexible AC Transmission Systems (FACTS).
• Applications in power distribution include DC-DC converters, Dynamic filters, frequency conversion and Custom Power Devices.
