Minimization of the power losses in deflection circuit

Horizontal deflection: By increasing the horizontal scanning frequency from 16 to 32kHz the losses in the windings and in the ferrite shield around the deflection coils increase considerable. To understand and describe these phenomena is very difficult but it's necessary in order to allocate direction for energy reductions. Mathematical models of the energy losses in the windings, the ferrite shield, and in the ferrite core in frequency and time domain will be made. Based on experimental results and the model improvements on the deflection coil and the linearity coil and advised. Vertical deflection: As the vertical scanning frequency is 50Hz there are not the same type of losses as in the horizontal deflection coil. But the current waveform has a saw-tooth shape demanding a lot of the power amplifier driving the vertical deflection coil. Switch-mode technology will be introduced in order to save energy. The great challenge is that the high frequency switch rippe current very easy can distort the picture quality
