Abstract :
It is shown, using a line power circuit, that the simplest possible cycloconverter, with only one thyristor, fills the deflection requirements during the vertical trace time and allows a short resonant flyback. Because the active components work in switched mode, they do not need any heat sink. The high efficiency provides an 8-W reduction in consumption at the mains. The short flyback time makes the converter especially attractive for future 32-kHz flicker-free TV sets
