2. Selenium rectifier - Wikipedia

   en.wikipedia.org/wiki/Selenium_rectifier

   An 8-plate 160 V 450 mA Federal brand selenium rectifier. A selenium rectifier is a type of metal rectifier, invented in 1933. [1] They were used in power supplies for electronic equipment and in high-current battery-charger applications until they were superseded by silicon diode rectifiers in the late 1960s.

3. Rectifier - Wikipedia

   en.wikipedia.org/wiki/Rectifier

   Typically these rectifiers were made up of stacks of metal plates or washers, held together by a central bolt, with the number of stacks determined by voltage; each cell was rated for about 20 V. An automotive battery charger rectifier might have only one cell: the high-voltage power supply for a vacuum tube might have dozens of stacked plates ...

4. Metal rectifier - Wikipedia

   en.wikipedia.org/wiki/Metal_rectifier

   Selenium Rectifier. 8-plate 160V 450mA Federal-brand. A metal rectifier is an early type of semiconductor rectifier in which the semiconductor is copper oxide, germanium or selenium. They were used in power applications to convert alternating current to direct current in devices such as radios and battery chargers.

5. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

6. Power electronics - Wikipedia

   An HVDC thyristor valve tower 16.8 m tall in a hall at Baltic Cable AB in Sweden A battery charger is an example of a piece of power electronics. A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of ...

7. Ripple (electrical) - Wikipedia

   en.wikipedia.org/wiki/Ripple_(electrical)

   The ripple voltage output is very large in this situation; the peak-to-peak ripple voltage is equal to the peak AC voltage minus the forward voltage of the rectifier diodes. In the case of an SS silicon diode, the forward voltage is 0.7 V; for vacuum tube rectifiers, forward voltage usually ranges between 25 and 67 V (5R4). The output voltage ...
