300V AC\DC Variable Power Supply
This 300V AC/DC variable PSU is designed for our vacuum-tube, MOSFET and some IGBT related experiments. This PSU consist with 0-300V Variac (variable auto-transformer),
700VA isolation transformer
, which is described in
and high voltage AC-DC converter. Because of the size and weight of these equipment’s we build this PSU as three separate units.
Complete view of 300V AC/DC variable power supply unit.
This PSU is capable to supply 20V - 300V 2.3A (max.) output in either AC or DC form. This PSU use high voltage and because of that, all the proper construction and precautions are necessary to take. Improper wiring or construction may leads to lethal electrical shock and/or fire. If you are not familiar with high-voltage practices do not attempt this project at home.
