Abstract

IT IS AN OBJECT OF THE INVENTION TO TRANSMIT AN INFORMATION INDICATING THE AMPLITUDE OF THE OPERATING VOLTAGE OF THE SECONDARY SIDE TO THE PRIMARY SIDE OF THE TRANSFORMER (TR) WITHOUT USING AN A ADDITION AL TRANSFORMER.BY A SWITCH (T2) AT THE SECONDARY SIDE ENERGY IS TRANSFERRED IN REVERSE DIRECTION IN FORM OF A REVERSE CURRENT (IT2) FROM THE SECONDARY SIDE INTO THE TRANSFORMER (TR). FROM THE VOLTAGE (U2) INDUCED BY THE REVERSE CURRENT AT THE PRIMARY SIDE THE CONTROL VOLTAGE (UR) FOR CONTROL OPERATION IS DERIVED.ESPECIALLY SWITCH MODE POWER SUPPLY FOR A TELEVISION RECEIVER OR A VIDEO RECORDER.(FIG. 1)
