High power factor soft switching three phase rectifier

摘要

This research is about rectifier,The 3-turn power supply (AC) is connected to the diode through the inductor (LL), and the diode is connected,The diode (DD) is connected to the diode (d) and the switch (s) through the inductor (LL),In each branch, the diode (DD) switches (s) and the diode (d) and the buffer (c) are arranged in parallel,Parallel structure of switch (s), diode (d) and capacitor (c),The switches (s), diodes (d) and buffers (c) are connected in parallel,Sound and switch (SS) of the above diodes,(S) The capacitor (c) is connected between them. The phase of input voltage and input current is maintained on the copper image. It can be switched between zero voltage and flexible current. The reversibility is realized and the power loss and pressure of switching elements are reducedNot only that, in the need to improve the reverse rate of various power supply equipment or emphasize the use of explosion-proof, the components that can be effectively used to reduce pressure and prolong the life of the equipment have the advantage of high-power soft switching three-phase rectifier.
