Bidirectional against clock flow transducer and method for its operation

摘要

The present invention relates to a bidirectional against clock flow transducer (1) with an input stage (2) for converting a first dc voltage into a first alternating voltage, a a primary winding (3) and a secondary winding (4) having a transformer (5) for the transmission of the first ac voltage into a second ac voltage (u0) and an output stage (6) for converting the second alternating voltage (u0) in a second dc voltage (u_From).In order to achieve that the against clock flow transducer (1) is of simple construction and has an output current, its ripple is less than in comparable known against clock flow wall, the invention proposes that the against clock flow transducer (1) to build up symmetrically, whereby both the input stage (2) as well as the output stage (6) as h - switch bridges being (12, 15) with before - or downstream lc - members (9, 19) is designed. For the operation of the counter clock flow transducer (1), in each case two half conductor switching element pairs (s1, s4; s2, s3 and s5, s8, s6, s7) in the two h - switch bridges being (12, 15) with the aid of a control device (13) are arranged alternatingly on - and is switched off, so that the transformer during a first time interval t1 in a first direction and during a second time interval t2 = t1 in the opposite direction is flooded, wherein the duty cycle d 1 is selected.
