power rectifier การใช้

Detector and power rectifiers could not amplify a signal.
Before the development of silicon power rectifier diodes, cuprous oxide and later selenium was used.
High-power rectifiers, such as those used in high-voltage direct current power transmission, employ silicon semiconductor devices of various types.
Power rectifiers, using copper oxide and selenium, were developed in the 1920s and became commercially important as an alternative to vacuum tube rectifiers.
Later models were built inside very large Hackbridge-Hewittic ( H-H ) vacuum tubes, which the company originally designed for use as high-power rectifiers in power supplies.
