FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment, to resonant transformers, and can be used in radio equipment devices for the frequency conversion and electrical energy transmission. Resonant transformer comprises primary winding connected to the power source via the electromagnetic resonance element, connected to the load secondary winding, and the resonant winding. Providing the electromagnetic resonance element contains bipolar transistor, which one output is grounded, and the base-collector junction capacitance is connected to the power supply through the potentiometer, in-series connected to the resistor, which output is grounded. Secondary and resonant windings have the same parameters and are wound in the form of cylinder on the dielectric with copper wire turn to turn tightly in one layer and are located on the same axis. Above the resonant winding consisting of four spaced turns primary winding is located. Transformer additionally contains three toroidal windings, two of which are oppositely interconnected and wound on the ferrite in the form of torus in opposite directions, and the third one is tightly wound turn to turn above them. Toroidal windings are located between the secondary and resonant windings and are centered relative to them. Secondary winding is connected to the first diode bridge input, which one output of is grounded through the power supply housing and the resonant winding lower end, and the second one is connected to the field effect transistor source. In parallel to the first diode bridge outputs, capacitor and resistor are connected. Field-effect transistor gate is connected to the powered by the common power circuits nanosecond pulses generator. Field effect transistor drain is connected to the throttle, connected to the third toroidal winding first end and to the second diode bridge input. Winding second end is connected to the power supply housing and to the second diode bridge input, which outputs are connected to the load. In-parallel to the second diode bridge outputs capacitor is connected, performing the power filter function, and to the second diode bridge input, which outputs are connected to the load, at that, to the second diode bridge outputs performing the filter function capacitor is in-parallel connected. Thus, the authors propose resonant transformer, which enables increase in the device operation efficiency due to the power supply mains power consumption reduction, possibility of the electromagnetic oscillations frequency adjustment during operation and uninterrupted operation in the event of short-term power surges.

EFFECT: technical result consists in increase in the efficiency due to the power consumption reduction, electromagnetic oscillations frequency adjustment during operation and uninterrupted operation in the event of short-term power surges.
