Reversibly DC converter inverter transformer-LINK HIGH FREQUENCY

摘要

The invention relates to electrical engineering and electronics and pulse power it can be used to create aviation-board power supply systems perspective planes (all-electric). The technical result of proposals is to increase the reliability of the device - namely, heat resistance, reliability and service life due to the exclusion of electrolytic capacitors, as well as emergency survivability by backup power interconnection channels.; Said technical result is ensured by the fact that in a reversible converter DC voltage to the inverter-bridge high frequency transformer having input terminals 1-2 for connection of the primary DC source, «n» pairs of output terminals 3-4, 5-6, 7- 8 for connection of loads, reversible inverter-rectifier 9, a transformer 10 with a primary winding 11 and «n» the secondary windings 12, 13, «n» reversible rectifier switches 14, 15, the input capacitor filter 16, «n» output filters 17 , 18, 19, schuntiru boiling respective pairs of output terminals of the device, and a control circuit 20 connected its main output leads to the control terminals rectifier inverter connected to its input terminals with the terminals of the input capacitor filter and the input terminals of the device, and output - with primary winding terminals of the transformer, and the control terminals of switches, rectifiers, each connected to its input terminals with corresponding terminals of the secondary windings of the transformer and the first output terminal - with a first an output terminal device of the corresponding pair, introduced «n» pulse modulators 21, 22, 23, each of which consists of two electronic switches 24, 25, diode 26 and inductor 27 connected to its first terminal to the connection point of the second output terminal of the corresponding switch rectifier the first terminal of the first electronic key, its second terminal connected to a corresponding output terminal of the second device, and its second output - to a connection point of the diode and a second oppositely electronic key, in extreme water which bypass the respective pair of output terminals of the device, and the control circuit being configured to pulse-width modulation of pulse signals at its input into it additionally modulating output terminals connected to control terminals of keys pulsed modulators.; As to formula 1 p, Fig - 1.
