The high-frequency rectifier power supply shares a single-phase bridge rectifier circuit with you

  Capacitive load single-phase bridge rectifier circuit: its four arms are composed of four diodes, when the 1st end of the transformer B secondary is positive and the 2nd end is negative, the diodes D2 and D4 are turned on due to the positive voltage, and D1 and D3 are cut off due to the reverse voltage. At this time, the current passes from the first end of the transformer through D4 through RL, and then through D2 back to the second end. When the first terminal is positive, the diodes D1 and D3 are turned on, D2 and D4 are cut-off, and the current flows through the RL through the 2nd terminal through D3, and then returns to the 1st terminal through D1. Thus, as with full-wave rectification, there is a positive and negative half of the cycle in which the current flows through the load, and always in the same direction
