Since the polarities of the output dc signals of the positive half cycle and the negative half cycle of the bridge rectifier circuit are the same, the polarities of the output dc signals can be the complete positive pole or the negative pole, if the directions of the diodes are reversed, a complete negative dc voltage is obtained, on the basis, a complete negative dc voltage is obtained through at least four rectifier diodes D6 and D6A, D and A, D8, the complete input of the negative dc voltage is ensured, a winding formed by the 10 pin, the 11 pin, the 8 pin and the 9 pin of the transformer T1 is connected to one side of a diode bridge network formed by four rectifier diodes D6 and D6A, D and A, D, a load is connected to the other side, in the half-wave rectifier, only one half-cycle of the input ac signal is allowed, and the remaining half-cycle of the input ac signal is blocked, in the process, almost half of the applied input power is wasted, however, in the bridge rectifier circuit, the current is allowed during both the positive half-cycle and the negative half-cycle of the input ac signal, so the output dc power is almost equal to the input ac power, and in addition, the half-wave rectifier has fewer parameters of the implementation specifications of the bridge rectifier, compared with the bridge rectifier, the bridge rectifier has fewer parameters: vin=170 VAC-264VAC vout=220v2.8a18v1a.
