Powerful Optocouplers Based on Tubular Lamps

A coaxial scheme for the construction of optocouplers using tubular lamps and photovoltaic cells is proposed, according to which the optocouplers have a cylindrical shape, and the optical radiation source (tubular lamp) is placed in them on the axis of a cylindrical housing, on the side surface of which photovoltaic cells are located. The designs of optocouplers with tubular xenon arc or LED lamps (as a source of optical radiation) and solar cells (as photovoltaic converters) constructed according to this scheme are described. It is shown that the level of radiant energy losses in the optocoupler of the proposed design can be lower than 30 %, and its output electrical power can reach 20 kW or more.
