Bidirectional increasing / decreasing DC / DC converter with magnetically coupled coils

摘要

Bidirectional increasing / decreasing DC / DC converter with magnetically coupled coils , consisting of a supply unit ( 1 ) , the primary filter housing ( 2 ) , the primary transistor T1 ( 3 ) and the secondary transistor T2 ( 7 ) , which are connected magnetically linked inductance ( 4 , 5) with bifilar windings , i. e . with windings with opposite orientation of winding , which is created autotransformer with a common point of start and end of the both inductance ( common ground ) . At output part is the secondary filter ( 8 ) and appliance ( 9 ) . Bidirectional increasing / decreasing DC / DC converter is controlled via a control circuit ( 11 ) , which through sensing and monitoring devices ( 12 ) senses the voltages and currents at the primary and secondary side of the converter and generates switching pulses for both transistors which operate complementary. Switching pulses are amplified using the driving circuits ( 10 ) . It may be modified by disconnecting a common start and end points of the two winding coils by means of the switch ( 6 ) , than the final solution will be completely electrically isolated .
