Abstract
A synchro power amplifier and control circuit for an inductive load has a plurality of synchro leg amplifiers connected to the load. Each amplifier has an interstage transformer for deriving samples of current drawn by the load. A multiplicity of capacitors are respectively connectable in parallel with the (load) upstream of the amplifiers by switches in a circuit 10 responsive to the voltage/current phase angle of the power driving the load, to compensate for the inductance of the load.
