摘要： A solid-state switch in a deflection circuit includes a plurality of field-effect transistors (Q7, Q8, and Q9) connected in series. Each of the transistors (Q7, Q8, and Q9) is part of a switching module (20, 22, and 24) in the form of a three-terminal transistor circuit. Two of the modules (20 and 22) are connected to a common gating terminal (12) solely by diodes (D6 and D7) oriented so as (a) to conduct current in the direction required to provide a turn-on signal for the transistors (Q7 and Q8) but (b) to isolate the common gating terminal (12) from the high voltages experienced by the transistors (Q7 and Q8) when they are in their non-conducting states.

摘要： A horizontal deflection circuit which including a horizontal output transistor; a damper diode connected in parallel with the horizontal output transistor; a resonant capacitor connected in parallel with the damper diode; a horizontal deflection coil connected in parallel with the horizontal output transistor; and a series resonant circuit connected in parallel with the resonant capacitor. The series resonant circuit is constituted by a series connection of a capacitor and an inductor to perform composite resonance in cooperation with the resonant capacitor. The capacitor and the inductor of the series resonant circuit are designed to have a tertiary resonant frequency. The composite resonance by means of the series resonant circuit and the resonant capacitor enables the top of the flyback pulse to be flattened, so that the waveform of the flyback pulse becomes near the form of rectangular wave. Accordingly, a horizontal deflection circuit having higher retracing capacity can be provided through the same horizontal output transistor as generally used in the prior art.

摘要： First and second gate-controlled switches are connected analogously to a Darlington transistor pair with a slow-response diode connected to delay application of a turn-off signal to the second gate-controlled switch until the first gate-controlled switch is fully turned OFF. The Darlington-type connection reduces a drive current required from a driving source to maintain the second gate-controlled switch fully ON for passing a load current therethrough.

摘要： A source of unregulated direct voltage has a terminal coupled to a capacitor. A horizontal deflection circuit is coupled to a first terminal of the source and to the capacitor so as to be energized by a regulated voltage established by the difference between the unregulated voltage and the voltage across the capacitor. The deflection switching transistor is serially coupled with an additional controllable switch, and an inducator is coupled between the junction of the switches and the second terminal of the source of unregulated direct voltage to provide a controllable path for current flow in the capacitor. The controllable switches are operated at the deflection rate to generate deflection currents and to control the state of charge of the capacitor to maintain a constant regulated voltage. The energy represented by periodic discharge of the capacitor is recovered.

摘要： A source of unregulated direct voltage is commutated at the horizontal rate by a two-transistor switching regulator and applied across a transformer primary winding. The duty cycle of the alternations is controlled to maintain the peak-to-average value of a first portion of the alternations at a constant value. A rectifier serially coupled with a capacitor is coupled across the secondary winding of the transformer and produces a direct voltage across the capacitor from the first portion of the alternations. The junction of the rectifier and secondary winding is grounded. A television horizontal output transistor has its emitter grounded and its collector coupled through an inductance to the other end of the rectifier. A constant energy is stored in the inductance during each deflection cycle for application to the horizontal output stage. The horizontal output transistor is one of the two regulator transistors.
