Design of a Negative-Impedance Converter and Its Application for a TV Deflection Circuit

Most horizontal deflection circuits used in TV cameras or TV receivers are deflection circuits operated by the switching function of transistors. This type of circuit is well known as an efficient deflection system having less power consumption, however, because there is a resistance existing in the deflection coil or within the circuit, it has a defect in that distortion is liable to occur in the deflection current. In order to improve the linearity of this deflection current, various methods were offered in the past, however, nothing definite has been found to solve this problem.
