FIELD: radio broadcasting, communication. SUBSTANCE: powerful key amplifier includes former of stepped voltage built on cells connected in series in D C circuit. Power inputs of each cell are linked to proper secondary winding of power transformer. Control unit is made in the form of multiphase pulse-duration modulation former. Thanks to this all cells are loaded evenly. EFFECT: enhanced operational stability. 3 dwg
