Patent ID: 7102431

Claim:
Method for generating a high-power alternating voltage amplified by switching, that follows a digital input data stream in terms of shape and amplitude, whereby direct current from a direct-voltage supply fed from a sine-shaped current is provided as the power supply, and a digital signal that corresponds to the ripple of the direct current is mixed into a signal that corresponds to the input signal, wherein the input data stream is converted into a digital signal sequence ( 1 , 1 ′, 4 ), and this signal sequence ( 1 , 1 ′, 4 ) is amplified by switching, whereby a digital signal ( 11 , 21 , 21 ′) is derived from the amplified output signal ( 6 ), and compared with a digital signal ( 1 , 1 ′, 4 ) that corresponds to the input data stream, and the amplification of the input data stream is influenced, in the sense of a congruency of the amplified signal with the input data stream, by means of switching by a digital difference signal that might be determined.
