Abstract
PURPOSE:To improve the cost, power consumption, linearity of the horizontally deflected current, and so on, by making the power source circuit and the horizontal output circuit of the television receiver into one body. CONSTITUTION:The transformer with exciting coil N1 and oscillating coil N2 wound around is provided which consists of the magnetic core having the nonlinear region having coil NC which controls the magnetic flux dependent upon these coils N1 and N2. Coil Nr and transistor Q1 are connected to DC power sources 21 and 22, and turning-on and off of transistor Q1 are controlled by the horizontal period (23, 24). Rectifying circuit 25 is connected to coil N2 to take out a DC output voltage, and this voltage change is detected and is supplied to coil NC. The operation point of the magnetic core is controlled by this detection output and the magnetic flux dependent upon coil NC to control the DC output voltage above to a prescribed value, and one end of coil N2 is connected to the horizontal deflecting coil through a capacitor or a diode to supply a saw tooth wave current to this horizontal deflecting coil.
