The circuit for reducing switching losses of the secondary switches in the indirect DC converters with the width control

摘要

The circuit for reducing switching losses of the secondary switches in the indirect DC converters with the width control (30) consists of the series connection of the condenser (15) and the diode (16), that is parallel connected to the first secondary switch in series with diode (17). The condenser (15) is parallel connected to the secondary switch (18), the inductor (19) and the diode (17). The circuit for reducing the switching losses of the secondary switches in indirect DC with width control (31) is in the same arrangement. It is connected in parallel to the second secondary switch (13), being in series with the diode (14) in bridge connection of the secondary rectifier.
