The high-frequency rectifier power supply shares the three-phase full-wave rectifier circuit with you

  Three-phase full-wave rectifier circuit: The three-phase full-wave rectifier circuit is actually composed of two sets of three-phase half-wave rectifiers in series. The first set of three-phase half-wave rectifier is composed of transformer secondary coils L1, L2, L3 and rectifier tubes D1, D2 and D3, and the second set of three-phase half-wave rectifier is composed of L1, L2, L3 and D4, D5 and D6. At the beginning, the maximum positive voltage relative to point 0 is in phase C, and the maximum value of negative voltage is in phase B. The current flows from point 0 through L3, D3, A+, loads L, R, B-, D5, L2 and back to point 0. If phase A is the next instantaneous, the load current will move from phase c to phase a, and the current will flow back to point 0 along point 0, D1, A+, load L, R, B-, D5, L2. In the same way, the operation of the three-phase full-wave rectifier can be analyzed every 60°
