A HIGH EFFICIENCY RINGING GENERATOR ABSTRACT OF THE INVENTION An improved ringing generator is disclosed, for producing and transmitting an AC ringing voltage waveform to a subscriber line from a negative and positive DC voltage source. The ringing generator is characterized by a transformer having a primary winding and a secondary winding. The primary winding includes a plurality of taps dividing the primary winding into a plurality of winding segments. The secondary winding is connected to subscriber line via a filter network. Each winding segment is connected to a buffer-driver which has a first lead connected to the DC voltage source and a second lead connected to a source of control signals. Responsive to the control signals a selected pair of buffer-drivers are alternatively enabled connecting for a predetermined time period the associated coupling segments to the DC voltage source thereby, producing a switched ringing voltage waveform which is coupled to the secondary winding.
