Resonant transformer - a transformer in which at least two windings, each of which is included in the oscillatory circuit with close or equal resonant frequencies . The classic high-frequency resonant transformer is the Tesla transformer . Resonant transformers are used in radio electronics (usually as parts of antenna devices) and in power electronics.
Features of resonant transformer cores
If a core is used in a resonant transformer, then certain requirements are imposed on it. The core should not be integral, but divided into parts, and each part has its own winding. For example, if the core is iron and made of solid plates and there is no screen between the windings, then resonance on such a transformer cannot be obtained. Therefore, in the manufacture of transformers on toroidal cores, they should be divided into two parts and on each part winding its winding separately from the other. With solid plates in the core, a very high-quality and grounded screen should be made between the windings, otherwise the resonance will not work. The resonance ideally works on transformers, in which each winding is on a separate core, and the cores are isolated from each other.
