POWER AMPLIFIER Russian patent published in 1994 - IPC

Abstract RU 2022450 C1

FIELD: radio engineering. SUBSTANCE: power amplifier is formed by two parallel channels; one of them is built around pulse-width modulated amplifier with inductive output filter connected at its output; other channel incorporates linear amplifier whose output is connected to point of connection of output filter and load. EFFECT: provision for operation as amplifier and as generator, reduced noise and harmonic factor, enlarged passband, reduced heat loss. 1 dwg
