Electrical energy is used in almost every modern industry, from manufacturing plants and transportation systems to renewable energy installations and electronic equipment. However, electrical devices often require different voltage levels, current types and power characteristics to operate efficiently. Power electronics makes this possible by using semiconductor devices and electronic circuits to convert and control electrical power.
M.Tech in Power Electronics is a postgraduate engineering specialisation that focuses on the design, analysis, control and application of electronic systems used for power conversion. It combines electrical engineering, electronic circuits, control systems, semiconductor technology and advanced mathematical methods.
The specialisation has applications in electric vehicles, industrial motor drives, renewable energy systems, battery charging, power supplies, smart grids and energy storage. Students may study power converters, inverters, rectifiers, switching circuits, digital control and electrical drive systems.
This programme can be suitable for engineering graduates interested in electrical energy conversion, electronic power systems and advanced engineering research. This guide explains its eligibility, duration, subjects, admission process, practical learning, career opportunities and future study options.
M.Tech in Power Electronics is a postgraduate engineering programme or specialisation focused on controlling and converting electrical power through electronic devices and circuits.
Power electronics systems use semiconductor components such as diodes, thyristors, MOSFETs and insulated-gate bipolar transistors (IGBTs) to regulate electrical energy. These components are used in circuits that convert alternating current (AC) into direct current (DC), DC into AC, or one DC voltage level into another.
For example, an electric vehicle battery stores energy as DC, while certain motor systems require controlled electrical power to operate. Power electronic converters help manage the electrical energy supplied to the motor. Similar technologies are used in solar inverters, industrial drives, battery chargers and uninterruptible power supplies.
The programme generally covers:
Power semiconductor devices
AC-DC and DC-AC converters
DC-DC conversion systems
Switching power supplies
Power converter control
Electric machines and drives
Digital control of power electronic systems
Renewable energy conversion
Electric vehicle power systems
Power quality and electrical system applications
The exact programme title varies. Some institutions offer M.Tech in Power Electronics, while others combine the subject with Electrical Machines and Drives, Power Systems or related areas. Applicants should compare the actual curriculum and degree title before applying.
