Pulse Flyback Transformer
Pulse Flyback Transformers operate in different modes. Some operate in CCM, while others operate in DCM. Depending on the application, a transformer can operate in either mode. If it does, a pulse form will be generated from the flyback energy. It will then discharge to the primary coil of a pulse transformer 185.
Pulse flyback transformers are often equipped with extra windings. The extra windings help to produce a large voltage pulse as the magnetic field collapses. Since the magnetic field has a high energy capacity, coupling it out through the additional windings helps the magnetic field to collapse faster and avoid voltage flash over. The pulse train produced by the flyback transformer's windings is then converted to direct current through a half-wave rectifier. A full-wave design is not necessary, since the transformers produce only pulses of several volts.
A new design has made the transformer even more effective by reducing the capacitance. This new technology is known as "close-coupled layer-wound" technology. The name "ringless" is used in reference to the fact that there are no ring-shaped parts on the transformer.
The high-voltage flyback transformer is controlled by a pulse-width modulation circuit. The control circuit determines the output frequency and the level of high voltage. The invention allows tight regulation over a wide input voltage range. A flyback transformer can be used in different applications, including pulse-width regulation and high-voltage power supplies.
The output voltage of the transformer can range from 10 to 20 kV. In nature, high-voltage is not sinusoidal but rather in the form of an arc. This is the result of two highly conductive bodies placed close together. The arc causes ionization of air in between. In some cases, it is caused by a corona phenomenon.
The high-voltage flyback transformer has two parts: the primary winding and the secondary winding. These are connected to a high-voltage capacitor 108. The capacitor stores energy during the clamped negative excursion of the flyback pulse. The output voltage can be adjusted by varying the winding's number of turns. The boost circuit can also operate without the boost function, but this operation requires a reduction in input current.
The primary winding of the flyback transformer is connected to the DC power source via a solid state switching circuit. The primary winding receives a control signal from a switching controller (122). This control signal decouples the flyback transformer from the DC power source when the primary winding current reaches a desired level.
The flyback transformer is a hybrid of a DC flyback transformer and an AC flyback transformer. Both types are similar except that the low voltage windings are insulated by paper. While the primary winding is connected to the secondary with a metal clamp, the lower voltage winding is covered with paper, which is referred to as the "evil core."
