Technical Electrodynamics| Zusammenfassung: | Requirements for semiconductor power converters with a high level of load current have been formulated. A review of research works addressing the problem of achieving maximum efficiency in DC voltage regulators using synchronous rectifiers based on modern field-effect transistors has been conducted. The proposed methods of synchronous rectification in pulse DC voltage stabilizers utilizing high-frequency magnetic amplifiers are described. These methods rely on the use of existing signals within the converter and eliminate the need for additional components or specialized drivers in their circuitry. The principle of operation is explained, and theoretical oscillograms are provided, which are validated by experimental data. Experimental results on the efficiency of such converters are presented. Specifically, the proposed methods of synchronous rectification in a pulse DC voltage stabilizer based on high-frequency magnetic amplifiers, with an output power of 300–400 W and input DC voltage of 310 V (equivalent to an industrial-frequency network), achieved an efficiency of 95%.
