Title: Method for providing synchronization and phase coincidence of transistor direct-voltage converters and a device for realization of the method
Inventor: YASKIV VOLODYMYR IVANOVYCH
Filed: 1998-03-12
Abstract: The proposed method for providing synchronization and phase coincidence of transistor direct-voltage converters can be employed in secondary power supply units. According to the proposed method, several identical direct-voltage converters are used. Each of the converters is designed as a push-pull generator with a voltage feedback circuit containing a resistor connected in series with the control transformer winding that is short-circuited by a saturating choke. The windings of all of the chokes are placed on a common magnetic core. On the core, an additional winding is provided. The additional winding terminals are connected together via two reverse-parallel-connected diodes. The proposed design provides for equal rate of magnetic reversal of all the saturating chokes. As the result, it is possible to remove variations of the switching parameters of the power transistor switches that can occur in dynamic operation modes and under nonuniform loading of the converters.
