Study Notes
Power Electronics Devices
- The most typical power electronics device found in consumer electronic devices is the AC/DC converter (rectifier).
- In the past, high-power electronic devices used were mercury arc rectifiers, thyristors, and diodes.
Variable Speed Drives (VSDs)
- The common application of VSDs in industry is to control the speed of AC motors, resulting in energy efficiency and improved process control.
AC/DC Converter (Rectifier)
- The power range of the AC/DC converter (rectifier) in consumer electronic devices is typically in the range of milliwatts to several hundred watts.
- The mercury arc rectifier was invented by Peter Cooper Hewitt, which was used to convert AC into DC.
