Questions and Answers
What is the difference between uncontrolled, semicontrolled, and fully controlled power semiconductor switches?
Uncontrolled devices cannot control turning ON and turning OFF, Semicontrolled devices can control turning ON but not turning OFF, and Fully controlled devices can control both turning ON and turning OFF.
What are the acronyms for the two types of fully controlled devices mentioned in the text?
MOSFET and IGBT
In what order did the evolution of power electronics devices occur, from diodes to fully controlled devices like MOSFET and IGBT?
Diodes, SCR's, MOSFET, IGBT
Study Notes
Power Semiconductor Switches
- Uncontrolled power semiconductor switches operate in only two states: fully on or fully off, and their state is determined by the circuit they are connected to.
- Semicontrolled power semiconductor switches have some control over their state, but their turn-off is not fully controlled, such as thyristors.
- Fully controlled power semiconductor switches have complete control over their state, both turn-on and turn-off, and can be switched on and off repeatedly, such as MOSFET and IGBT.
Fully Controlled Devices
- The acronyms for the two types of fully controlled devices are MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) and IGBT (Insulated Gate Bipolar Transistor).
Evolution of Power Electronics Devices
- The evolution of power electronics devices occurred in the following order: diodes, thyristors, bipolar junction transistors (BJT), MOSFET, and IGBT.
- This evolution led to increased control and efficiency in power electronics devices.
