  • Apparatus and method for converting electrical energy into heat energy
    Patent number: 4336444
    Abstract: A device and method for converting electrical energy into heat energy including a cascade connection of bidirectional thyristors, such as triacs, operated from an alternating current power supply. The thyristor are submerged in oil which is thermally conductive but electrically insulative, the oil being in initimate contact with the thyristors junctions. The heat energy at the junctions flows to the oil, from there to a heatsink (radiator), and from the radiator to the surrounding atmosphere.
