TRANSMITTER FOR SERVO SYSTEM Russian patent published in 2003 - IPC

FIELD: electrical engineering, applicable for transudation of the signal of a sine-cosine transformer to a signal of the selsyn in the flight vehicle automatic control systems. SUBSTANCE: in the transmitter for the servo system the SCT-transmitter is connected with the outputs via phase shifters, scalars to two summers with the signal sign taken into account. The sinusoidal output of the SCT-transmitter via a phase shifter and a power amplifier, as well as the outputs of the summers via power amplifiers are connected to the output of the transmitter for the servo system. A sinusoidal signal similar to the signal of the selsyn and matched in the phase and load is formed at its output. EFFECT: produced small-sized, reliable, simple in manufacture and economical device of the servo system taking into account the phase shift of the output signal of the SCT-transmitter relative to its supply voltage. 2 cl, 1 dwg
