It acts subsequently as a magnetic ballast so when a voltage transformer.

Other programs are short circuit-proof extra-low voltage transformers for toys or installments that are doorbell.

A resonant transformer is a transformer where both windings or one has functions as a tuned circuit and a capacitor across it. Resonant transformers can operate as Q_variable bandpass filters that are high. The transformer windings have either atmosphere or ferrite cores and the bandwidth can be corrected by altering the coupling (mutual inductance). They're also used in radio transmitters.

Resonant transformers can also be used in high voltage power supplies, and electronic ballasts for fluorescent lamps. They can be also used in some kinds of switching power supplies.Here frequently just one winding has a capacitor and acts as a tank circuit. A pulse or square wave drives the transformer for efficacy, produced by an oscillator circuit that was electronic. Each pulsation functions to drive sinusoidal oscillations that are resonant in the winding that is tuned, and across the secondary a high voltage can be developed due to resonance.
