Power Electronics
Every converter in this subject is built from devices that are never allowed to sit half-on, because that is the only way to move kilowatts without dissipating them. These topics animate the switching and the waveform it produces.

Why switching
The argument that decides the shape of every circuit that follows.
- Power diodes and their recovery
- SCR construction, triggering and commutation
- MOSFET and IGBT as power switches
- Switching losses and snubbers
- Heat sinks and thermal design
AC to DC: rectifiers
Taking a sinusoid and getting a usable DC level out of it.
- Single-phase half and full-wave rectifiers
- Controlled rectifiers and firing angle
- Three-phase rectifiers
- Effect of source inductance
DC to DC: choppers
Changing a DC voltage by chopping it and averaging the result.
- Step-down and step-up choppers
- Duty cycle control
- Buck, boost and buck-boost converters
- Continuous and discontinuous conduction
DC to AC: inverters
Manufacturing a sinusoid out of a battery and four switches.
- Single-phase bridge inverters
- Three-phase inverters and 180°/120° conduction
- PWM techniques and harmonic elimination
- Multilevel inverters
Applications
Where all of this actually ends up.
- AC voltage controllers and cycloconverters
- Switched-mode power supplies
- DC and AC motor drives
- UPS and solar inverters
