Thyristor sawtooth current generator with mains isolation - uses generating inductance for line deflection in TV receiver with periodically applied energy

摘要

The circuit feed energy is applied to the first inductance through a charge inductance and a device with controlled switches, with the supply source circuit and inductance circuit galvanically separated. The charge inductance consists of a transformer (6) whose primary winding (5) is periodically connected through a third switch (7) to the supply source (2, 3) and its secondary winding (20) is connected through a diode (23) to the first inductance (31) circuit (25-36). The secondary winding (20) forms with a capacitor (21) an oscillating circuit, in which the energy not taken up by the diode (23) oscillates until the next closing interval of the switch (7).
