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.

Basic concept of Power Electronics

Power Electronics (Definitions)

“Power Electronics may be defined as a field of Electrical Engineering in which the study of solid state devices which may be used for control and conversion of Electric Power of Very high range up to Kwatts or Mwatts is to be carried out.”

“Power electronics involves the study of electronic circuits intended to control the flow of electrical energy. These circuits handle power flow at levels much higher than the individual device ratings.”

Projects in Power Electronics Area

27

Present Trends in Power electronics

• The future will demand Integrated Systems for electronic power processing. A more multi-disciplinary approach is needed for new achievements in integration, packaging, reliability and cost reduction.

• Intelligent control and energy management will come easily. Thermal and

passive component integration is equally important.

• Large penetration of power electronics into power systems, mainly in distributed generation.

• Large-scale use of power electronics in automotive applications. This largely depends on political decisions as well as technology advances.

28

Present Trends in Power electronics

• Advances in high current, higher voltage devices will have a major impact on traction applications.

• Emerging applications in commercial / residential areas: HVAC, Induction cooking, lighting, computer power etc.

• The cost of using power electronics will depend on factors like:   • Recycling    • Standards regarding EMI    • Intelligence / protection    • Modular converters    • Reliability considerations    • Thermal engineering    • Electromagnetic Integration

• Silicon carbide is an important future development in power semi-conductors.

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.
