Diode rectifiers (3): With capacitive and inductive loads, waveforms, harmonic content.

Non-isolated dc-dc converters (7): Buck, Boost, Buck-Boost (principle of operation, continuous conduction mode, waveforms, volt-second balance, ripple current and voltage, condition for DCM, output to input voltage relation).

Isolated dc-dc converters (4): Need for isolated converters. Working principle of Flyback Converter and Forward Converter.

Inverters (7): 1-ph and 3-ph VSC topologies, sine-triangle PWM technique, applications of inverters.

Power generation and grid integration (7): Single synchronous generator connected to a load. Frequency and voltage control of the single generator with load. Single synchronous machine connected to an infinite bus. Power-angle curves. Reactive power control. Transmission line characteristics. Star-Delta transformers. Interconnected grids. Frequency control in interconnected grids.

Thyristors and HVDC (6): Thyristor based converters, rectifying and inverting mode of operation, waveforms with different loads. HVDC links — motivation and topologies: Line Commutated (Thyristor) Converter links and Voltage Source Converter based links.
