| 摘要 |
The invention relates to electrical engineering and electrical power engineering, namely to alternating current-to-direct current voltage converters.The converter comprises three branches, connected in parallel, the first of which consists of an electronic key (5) and a rectifier bridge (3), connected in series, at the same time to the terminals of the rectifier bridge (3) are connected in parallel an alternating current voltage source (1) and an upper harmonic filter (2). The second branch consists of a condenser (4), and the third - of a diode (7) and an electronic key (6), connected in series. The converter also comprises a radio-frequency transformer (9), the ferromagnetic core of which is made with a gap. The primary winding (8) of the transformer (9) has one end connected to the point of junction of the electronic key (5) with the rectifier bridge (3) and the other end - to the point of junction of the diode (7) with the electronic key (6). The secondary winding (10) of the transformer (9) is connected in series to an electronic key (11), in parallel to it being connected an upper harmonic filter (12) and the load (13). |
