Method for smooth switching of transistors of the three-phase, two-level voltage inverter and the system for smooth switching of transistors of the three-phase, two-level voltage inverter
Method for smooth switching of transistors of the three-phase, two-level voltage inverter and the system for smooth switching of transistors of the three-phase, two-level voltage inverter
the object of the application is the way and the soft switching transistors delta, two-tier falownika voltage according to the patent application, no p 412114 with three systems of identical for each phase, each transistor is falownika vid sau017cony in an additional system assisting his switching.thyristors (ty1, ty3, ty5, ty2, ty4, ty6) in combination of each phase are attached after the given time interval. switching transistors (t1 to moments corresponding t1, t3, t5, t2, t4, t6), and excludes spontaneously after reducing their electricity below the power support.a system switching transistors delta two-tier falownika voltage according to the patent application number.p 412114, in which the first collectors of transistors (t1, t3, t5) are connected to the positive voltage source via the first clamp fixed du0142awiku00f3w induction (l1a, l3a, l5a), and emitter transistors are connected through these second coils (segment of block l1, l3b, l5b) with clamping receiver and phase delta (a, b, c).the second transistors (t2, t4 collectors, t6) are connected through a third coils (l2b, l4b, l6b) squeezes receiver phase delta (a, b, c) and their emitters through the fourth coils (l2a, l4a, l6a) are connected to the negative voltage source dc clamp.the collectors of transistors (t1, t3, t5) are connected the first cathode thyristors (ty1, ty3, ty5) with interconnected feedback diodes (dty1, dty3, dty5), and these thyristors are connected through the first anode capacitors (c1, c3, c5) with anodami diodes (d1s, d3s, d5s) whose cathode pou0142u0105czon e are four days the first transistors (t1, t3, t5).the ends of the capacitors (c1, c3, c5) are connected with diodes diodes (d2z, d4z, d6z) whose anodes are connected to a negative source voltage clamp standing.the second transistors (t2, t4 collectors, t6) are accompanied by an anode of diodes (d2s, d4s, d6s) whose cathode are connected by second capacitors (c2, c4, c6) with diodes thyristors (ty2, ty4, ty6) with interconnected feedback diodes (dty2, dty4, dty6), a diode (cathode d2s, d4s, d6s) are connected also with anodami diodes (d1z, d3z,d5z) connected diodes with positive clamp voltage source standing, and anodes thyristors (ty2, ty4, ty6) are connected with four days of transistors (t2, t4, t6).
