CLASS d AMPLIFIER ON TETRODE Russian patent published in 1994 - IPC

Abstract RU 2007850 C1

FIELD: radio engineering. SUBSTANCE: class D amplifier has former of signal with pulse-duration modulation, powerful key amplifier on tetrode and load. Output of supplementary source of constant voltage is connected to anode of tetrode via diode fixing residual voltage across anode of tetrode in open state thus reducing current of shielding grid. EFFECT: reduced power dissipated across shielding grid of tetrode. 2 dwg
