Power Electronics

Devices first

This 25-lecture NPTEL course from IIT Delhi starts with the switching devices that power electronics depends on. The early lectures compare diodes, SCRs, triacs, GTOs, BJTs, MOSFETs and IGBTs, so you know what each device does before any circuit is built around it.

Converters and controllers

Once the devices are in place, the course moves to rectifiers, single-phase and three-phase, including controlled and dual-converter arrangements. Later lectures cover AC voltage controllers, cycloconverters and non-isolated DC-DC converters.

Points worth knowing

• Numerical lectures on devices and rectifiers reinforce the theory with calculations.
• The sequence runs from devices to converters, which suits a student who wants to see the building blocks in order.
• The listing ends at the first non-isolated DC-DC converter lecture, so check the rest before you plan around it.
