The invention relates to the electrical engineering and is meant for creating powerful, adjustable resonance voltage transducers of different application, namely for cathodic protection installations working at higher temperatures with self-cooling, welding converters and induction heating systems. The quasi-resonant direct-current voltage transducer contains a half-bridge support of transistors (1, 2), the collector of a transistor (1) is connected to a terminal of the primary windings (4-1, 4-2), connected in series opposition, of an output transformer (4), with a high prescribed value of mutual leakage inductance, the second terminal of which is connected to one terminal of a power supply (3), and the emitter of the second transistor (2) is connected to the second terminal of the power supply (3). The transducer also contains a resonance capacitor (5), one terminal of which is connected to the mean terminal of the half-bridge support, and the second - to the mean terminal of the primary windings (4-1, 4-2) of the output transformer (4), the outputs of the secondary windings of which, made with prescribed inductance value, are connected through rectifiers (6-1, 6-2) to a common load (7).
