Control method of indirect DC converter with soft switching with secondary controlled rectifier with two secondary switches

摘要

The control method of indirect DC converter with soft switching with secondary controlled rectifier with two secondary switches consist in the secondary switches (15) and (16) are switched on at the same time as opposed primary switches (3), (4) a (1), (2) of the inverter and are switched off sooner then the primary switches (3), (4) a (1), (2). The reduction to zero of the secondary transformer (8) current is achieved, so that is the primary current reduced to the magnetizing current. The current is better distributed in the primary and secondary switches an in the transformer, so the conductivity losses are lower and the efficiency of the converter is higher.
