Abstract
A high efficiency cathode-ray tube magnetic deflection circuit, providing a sawtooth current waveform at a frequency of 100 kilohertz that includes a FET transistor (11) connected to an anti-phased step-down transformer (15,16,17) for driving an output transistor (18). A co-phased step-up transformer (33,34,35) connected to the deflection yoke (19) provides deflection 'S' correction, and also a dynamic focus waveform. The transformers have litz wire windings.
