摘要： A method of operating a voltage reference element such as a zener diode comprises applying at least two current values to the device in respective periods of time one said value being such as to provide desired reference voltage characteristics of the device and the other being such that the average current during both periods provides a selected power dissipation to set a required temperature of operation of the device.

摘要： A power transformer intended for power coupling comprises two or more independent magnetic paths provided by relatively high permeability magnetic cores each of which is surrounded by one or more windings (primary, secondary) individual to that core, and at least one coupling winding forming a closed circuit that encloses said magnetic paths. Each core together with the winding or windings individual thereto is enclosed by an electrostatic screen. Each coupling winding is located externally of the screen that encloses the respective magnetic path. This arrangement minimises capacitative coupling between the respective transformer windings of the independent magnetic paths.
