The circuit arrangement comprises a parallel resonant circuit which incorporates a line deflection coil, a diode connected in parallel with the coil to conduct the deflection current during a first portion of each operating cycle, a second diode and a thyristor connected in series with one another in parallel with the coil, the thyristor being fired by pilot pulses to conduct the deflection current in a second portion of each cycle immediately following the first portion, a series resonant circuit including a capacitor connected in parallel with a thyristor for quenching the thyristor at the end of the second portion of each cycle and a third diode connected in series with the capacitor in a circuit branch connected in parallel with the second diode and serving to transfer energy from the series resonant to the parallel resonant circuit. The circuit offers the advantage that it may readily be adapted to permit modulation of the deflection current and to provide auxiliary voltages unaffected by such modulation.

摘要： A circuit for providing a saw-tooth current in a coil is described. The circuit comprises a trace condenser and a retrace condenser which form together with the coil a resonant circuit during the retrace interval, a diode connected parallel to the retrace condenser, a controllable switch connected to a supply source through an inductor and to the retrace condenser through a second diode.The main feature of this circuit is to comprise a condenser connected on one hand towards the controllable switch and the first inductor and, on the other hand, to a circuit comprising a second inductor and, through a third diode, towards the retrace condenser. The condenser and the two inductors are sized in such a manner that when the controllable switch is not conductive, energy is supplied to the condenser and that successively, when the controllable switch is conductive, the condenser is completely discharged through the second inductor. The energy thus stored in the second inductor is then supplied to a storage device.

摘要： A circuit for driving a saw-tooth current in a coil includes a deflection circuit formed by the coil connected in parallel with a retrace capacitor and in series with a trace capacitor. The deflection circuit is connected in parallel with a first diode which conducts during the first half of the trace interval and in parallel with a second diode connected in series with a controllable switch which conducts during the second half of the trace interval. While the transistor is conductive, current flows through an inductor connected in series with it. The energy stored in this inductor is transferred at a subsequent stage partly to the deflection circuit and partly to a further capacitor. The further capacitor subsequently itself transfers the charge stored in it through a second inductor and a fourth diode to the deflection circuit so that at no time is energy dissipated in a load.

摘要： A circuit for providing saw-tooth current, with a trace and a retrace interval, in a coil, in particular a deflection coil of a television kinescope, in which the coil is connected to a retrace condenser and a trace condenser so as to form a deflection circuit which oscillates freely during the retrace interval, is described. In this circuit, a first diode is connected parallel to the deflection circuit with such polarity as to be made conductive by the saw-tooth current during the first part of the trace interval, and the said deflection circuit is also connected parallel, by means of a second diode having such polarity as to be made conductive by the saw-tooth current during a second part of the trace interval, to a controllable switch, which is made conductive during part of the trace interval. The controllable switch is connected, by means of a first inductor, to a supply voltage source so that, during the interval in which the switch is conductive, energy is stored in the first inductor and later transferred, during the interval in which the switch is non-conductive, partly to the deflection circuit, by means of a third diode and partly to a first condenser. The main characteristic of this circuit is that means are provided whereby the energy transferred to the first condenser is subsequently restored to the supply source.

摘要： A circuit for providing saw-tooth current with a trace and retrace interval in a coil, in particular a deflection coil of a television kinescope, in which the coil is connected to a trace and retrace condenser with which it forms a resonant circuit, is described. In this circuit, a first diode is connected in parallel to the resonant circuit with such polarity that it is made conductive by the saw-tooth current during the first part of the trace interval, and the resonant circuit is also connected, through a second diode, to a controllable switch, which is made conductive at least during that last part of the trace interval, the second diode being connected with such polarity that it is made conductive by the saw-tooth current during the last part of the trace interval. The controllable switch is connected to a supply voltage source through a first inductor and part of the energy stored in the first inductor, during the interval in which the controllable switch is conductive, is transferred, during the retrace interval, to the resonant circuit through a third diode. The main characteristic of this circuit is that means are provided, connected in series to the second diode, the controllable switch, and the first diode, and a first condenser connected in series between the first diode and the second diode, to produce, at least during the conduction interval of the controllable switch, a d.c. voltage with substantially the same amplitude but with opposite polarity to the voltage produced at the terminals of the first condenser.
