Description of drawings
Fig. 1 is the circuit diagram of the active crisscross parallel soft switch circuit of booster type.
Embodiment
Referring to Fig. 1, the active crisscross parallel soft switch circuit of booster type comprises two inductance L that are coupled 1, L2, two sustained diode 1, D2, two power switch tube S 1, S2, the drain electrode of first power switch tube S 1 links to each other with the anode of the second diode D2 and an end of second inductance L 2, the drain electrode of second power switch tube S 2 links to each other with the anode of the first diode D1 and an end of first inductance L 1, the other end of first inductance L 1 links to each other with the other end of second inductance L 2, it is characterized in that the series circuit that constitutes by first capacitor C 1 and the first auxiliary switch S3 in 1 parallel connection of first power switch tube S, wherein the first auxiliary switch S3 is consistent with first power switch tube S, 1 direction, and first capacitor C 1 links to each other with the contact of first power switch tube S 1 and second inductance L 2; The series circuit that constitutes by second capacitor C 2 and the second auxiliary switch S4 in 2 parallel connections of second power switch tube S, wherein the second auxiliary switch S4 is consistent with second power switch tube S, 2 directions, and second capacitor C 2 links to each other with the contact of second power switch tube S 2 and first inductance L 1.
