Abstract
A device for the transmission of electrical power signals of variable frequencies and phases from a stationary assembly to a rotary assembly wherein the primary winding of a rotary transformer is supplied by an electrical power source of fixed frequency, and the power output from the secondary winding of the transformer is supplied to a chopping feed of a signal generating system including a digital memory storing a digital signal having the desired characteristics of the signal to be generated, a digital-to-analogue converter for receiving the digital signal from the memory under the control of a clock pulse generator, and an amplifier connected to the converter to give the desired power to the analogue signal received from the converter.
