Abstract

PURPOSE:To establish the vertical deflection circuit of switching system in low power consumption, by alternately turning on and off the pump up power supply and scanning power supply during scanning period and blanking line period. CONSTITUTION:The output of the vertical oscillation circuit 1 is fed to the vertical deflection coil Vco via the saw tooth wave generation circuit 3, amplifying circuit 4, pulse width modulation circuit 5, and switching output circuit 6. A part of the vertical deflection current is negative fed back to the amplifier 4. The comparator COMP compares the voltage dividing the output of the output circuit 6 with the scanning power supply Vcc, and produces an output when the voltage at the input terminals A and B is B>=A. The logical sum circuit 2 receives the output of the oscillation circuit 1 and the output of COP to control the switch circuits S1 and S2. As a result, to the switching output circuit 6, the scanning power supply Vcc is surely fed during scanning period and the pump up power supply Vr is during blanking period.
